How to Replace Avalon Pontoon Navigation Lights | Improve Night Safety and Visibility
The sun dips below the treeline, the lake turns to glass, and suddenly those old, dim navigation lights on your Avalon are barely visible — making you feel less like a captain and more like a liability waiting to happen.
TL;DR: Replacing your Avalon’s navigation lights is a straightforward DIY job that takes about an hour and dramatically improves night safety. Most Avalon pontoons use integrated light panels or surface-mount LED pods. The key steps: identify your light type (port/starboard integrated or separate pods), disconnect battery power, remove the old fixture (noting wire connections), install the new USCG-approved LED replacement, and test before sealing. This guide covers both integrated bow light panels and individual side lights, plus when to upgrade to modern LED for better visibility and lower power draw.
Key Takeaways:
- Always disconnect your battery before touching any wiring — marine electrical shorts are no joke
- Navigation light rules are strict — red must be on port (left), green on starboard (right), white on stern/all-around
- LED replacements draw 80-90% less power than incandescent bulbs and last years longer
- Take photos of wiring before disconnecting — you’ll thank yourself during reinstallation
- USCG certification is required for navigation lights to be legal on the water
- Corroded connections cause most light failures — not always the bulb itself
Why Working Navigation Lights Matter More Than You Think
Here’s the thing about night boating on an avalon pontoon boat — you’re wide, you’re stable, and you’re often carrying precious cargo (family, friends, good times). But without proper navigation lights, you’re invisible to other boats. And on a busy holiday weekend lake, invisible is dangerous.
Navigation lights aren’t just accessories. They’re legally required equipment. The U.S. Coast Guard requires all motorboats to display specific lights between sunset and sunrise . For a pontoon boat, that means:
- Red light on the port (left) side
- Green light on the starboard (right) side
- White light visible 360 degrees (either an all-around light or separate stern light)
Other boats see your red light and know they need to give way. They see your green light and know they have the right of way. It’s the language of the water after dark — and if your lights don’t speak clearly, you’re inviting trouble.
One boater shared: “I was out at dusk and my port light was out. A bass boat came out of nowhere and missed me by maybe 20 feet. He couldn’t see me until he was right on top of me. I ordered new LEDs that night.”
Do you know the last time someone checked your navigation lights from the water? Not from the dock — from where other boats actually see them.
What Type of Navigation Lights Does Your Avalon Have?
Avalon pontoon boats use two main styles of navigation lights, depending on the model year and series .
Integrated Bow Light Panel: Older and some mid-range Avalons use a single plastic panel that mounts flush into the bow deck. This panel contains both the red port light and a white anchor/forward light in one housing. It measures approximately 18.5 inches wide and requires a cutout of about 16.5 inches .
Separate LED Pods: Newer Avalon models (especially Excalibur and luxury series) use individual surface-mount LED pods — one red on the port side, one green on starboard . These are smaller, more modern, and easier to replace individually.
Stern/All-Around Light: Almost all Avalons have a removable white light pole that plugs into a socket at the stern. This is typically a separate replacement from the bow lights.
Pro tip: Walk to the front of your boat and look. Do you see one large cream-colored panel? That’s integrated. Do you see two small separate lights? That’s pods. Your replacement needs to match your style.
Which style is on your boat right now? Walk to the bow before you buy anything.
The USCG Rule: Don’t Buy Random Lights
Here’s where people mess up. You can’t just buy any red and green lights on Amazon. Navigation lights must meet US Coast Guard certification requirements .
What USCG certification means: The light has been tested to be visible from specific distances (usually 2 nautical miles for pontoon-sized boats) and at specific angles (112.5 degrees for side lights). A pretty light that doesn’t meet these specs is illegal — and if you’re in an accident with non-certified lights, your insurance might not cover you.
Where to find certification: Look for “USCG Approved” or “USCG Certified” on the packaging or product description. For integrated panels, the certification is built into the panel design. For pods, each pod should be individually certified.
What certified brands to look for: Attwood, SeaSense, Perko, and OEM Avalon replacements are safe bets . The OEM Avalon port light panel part number is 125190A if you want an exact factory match .
Are your current lights USCG certified? If you don’t know, check before assuming replacements are the right ones.
OEM vs Aftermarket vs LED Upgrade: Which Should You Choose?
OEM Replacement (Factory Original): The safest, easiest choice. Exact fit, exact wiring, zero guesswork. For integrated bow panels, OEM part number 125190A fits many Avalon models . The downside: you’re paying for old technology (incandescent bulbs) unless you find an OEM LED version.
Aftermarket Direct Replacement: Companies like Attwood and SeaSense make direct-fit replacements for common Avalon light panels. These are often LED instead of incandescent, which is a significant upgrade. Match your dimensions carefully — an 18.5-inch panel needs an 18.5-inch replacement .
LED Upgrade: This is what most owners should do. LED navigation lights draw 1/10th the power of incandescent bulbs, last 50,000+ hours, and are actually brighter. The catch: you need to ensure the LED fixture is USCG certified (most are now). DRSA offers USCG-compliant LED navigation lights specifically for Avalon pontoons .
What most experienced owners do: Replace the entire fixture with an LED version, not just the bulb. “LED bulbs in old housings often don’t project light at the correct angles,” one marine electrician explains. “The housing is designed for the filament position of an incandescent bulb. LED chips sit differently, so the light pattern changes.”
Is saving $20 worth potentially being invisible at night? Buy the right fixture, not just the cheap bulb.
Tools and Materials You’ll Need
Here’s what to gather before you start. Most of this is already in your toolbox.
Tools:
- Flathead and Phillips screwdrivers
- Wire strippers/cutters
- Crimping tool (or pliers if you’re careful)
- Multimeter or test light (for troubleshooting)
- Drill with bits (if mounting new screw holes)
- Marine heat shrink tubing (better than electrical tape)
Materials:
- Replacement navigation light fixture (USCG certified)
- Marine-grade butt connectors or solder seals
- Dielectric grease (prevents future corrosion)
- Stainless steel screws (if the new light doesn’t include them)
- Zip ties for wire management
Optional but recommended:
- Shop towel or rag (corrosion is messy)
- Headlamp (so you can see what you’re doing)
- Phone camera (to document wire colors before disconnect)
Do you have dielectric grease? If not, buy some — it’s the difference between a repair that lasts a season and one that lasts a decade.
Step-by-Step: Replacing Integrated Bow Light Panel
This is the most common replacement on mid-2000s to late-2010s Avalon pontoons. The panel sits flush in the bow deck, just behind the front rail .
Step 1: Disconnect the battery. Negative terminal first. This isn’t optional — marine wiring can short and cause fires or blown fuses.
Step 2: Access the back of the panel. You’ll likely need to remove a small access panel inside the bow storage compartment. Some Avalons have a dedicated removable section directly under the light. Look for screws or latches.
Step 3: Remove the old panel. From outside the boat, remove the screws holding the light panel to the deck. There are typically 8 mounting bolts on Avalon integrated panels . The panel should lift out — but the wires will still be attached.
Step 4: Photograph the wiring. Take a clear photo of which wire goes where. Red to red? Black to black? Or are there multiple wires? Don’t trust your memory.
Step 5: Disconnect the wires. Note the connection type. Older Avalon panels use single spade female connectors . You may need to cut and strip wires if the connector types don’t match your new light.
Step 6: Clean the mounting surface. Scrape away any old sealant or debris. The new panel needs a flat, clean surface to seal properly.
Step 7: Connect the new panel. Crimp or solder your connections. Use heat shrink tubing over each connection. Add a small dab of dielectric grease inside each connector before final crimping — this prevents future corrosion.
Step 8: Test before mounting. Reconnect the battery (negative last). Turn on your navigation light switch. Verify:
- Red light illuminates on port side (check from in front of the boat)
- Green light illuminates on starboard side
- White forward light (if your panel has one) works
- No dimming or flickering
Step 9: Mount the new panel. Apply a bead of marine sealant (like 3M 4000 UV) around the cutout edge. Set the panel in place. Install screws — stainless steel only. Wipe away excess sealant.
Step 10: Final test. Reconnect everything, turn lights on, and walk to the front of your boat. Can you clearly see red on the left, green on the right? Good. You’re done.
Step 11: Secure wiring. Zip tie any loose wires inside the access compartment so they don’t rub against sharp edges or moving parts.
One owner’s hard-won advice: “Don’t skip the dielectric grease. I replaced my bow lights twice in three years because of corrosion. Third time I used grease on every connection and they’ve been perfect for five seasons.”
Did you take that photo of the wires before disconnecting? Go back and take it now — future you will be grateful.
Step-by-Step: Replacing Individual LED Navigation Pods
Newer Avalon models (especially Excalibur and luxury series) use separate surface-mount pods for port and starboard lights . These are simpler to replace than integrated panels.
Step 1: Disconnect battery. Same rule applies — always.
Step 2: Identify which pod failed. Port (red) or starboard (green)? Replace in pairs if one is failing — the other isn’t far behind. Mixing old incandescent with new LED on opposite sides creates uneven visibility.
Step 3: Remove the old pod. There are usually two or three screws on the top or side of the pod. Remove them. The pod may have sealant underneath — gently pry it loose.
Step 4: Access the wiring. Wires run through a small hole in the deck or rail. You may need to access from underneath (through a storage compartment or under-deck panel).
Step 5: Disconnect and remove. Cut or disconnect wires close to the old pod. Leave enough wire to work with for the new connection.
Step 6: Connect the new LED pod. Most LED navigation pods come with pigtail wires. Connect:
- Black to black (negative/ground)
- Red to red or black/white stripe (positive for light)
- Some pods have a third wire for the white light — consult your manual
Step 7: Test. Reconnect battery. Turn on lights. Confirm the correct color illuminates and is visible from the front.
Step 8: Mount the new pod. Apply marine sealant around the wire hole. Position the pod. Screw in place with stainless screws. Do not overtighten — you can crack the plastic housing.
Step 9: Seal the edges. Run a small bead of sealant around the base of the pod where it meets the deck or rail. Smooth with a wet finger.
One pod or both? Replace both at the same time if one has failed. LED pods are cheap enough, and mismatched brightness or color temperature looks bad and might confuse other boaters.
Have you checked both sides recently? It’s easy to notice the broken one, but the other side might be dim without you realizing it.
Upgrading from Incandescent to LED: What You Need to Know
This is the upgrade most Avalon owners should do. Old incandescent navigation lights draw 10-25 watts per light. LED equivalents draw 2-3 watts. That’s less strain on your battery and less heat melting your light housings.
The brightness question: LED navigation lights are actually brighter than incandescent — but in a controlled way. USCG certification requires specific lumen outputs. A certified LED replacement meets the same visibility requirements as incandescent, just more efficiently.
Polarity matters with LED. Incandescent bulbs don’t care which wire is positive and which is negative. LED lights do. If your new LED light doesn’t work, try swapping the wires. You won’t damage it by reversing polarity on most marine LEDs, but it just won’t light up.
What about the stern light? Replace that too. Your stern/all-around white light should be LED. Most Avalons use a standard 2-pin pole light base — Attwood and Perko make direct LED replacements.
One owner’s experience: “I upgraded all my navigation lights to LED and the difference is huge. They’re noticeably brighter and my battery lasts way longer when anchored with lights on. Best $60 I’ve spent on the boat.”
Are you still running original incandescent bulbs? They’re probably dimmer than when new — and you don’t know what you’re missing until you see LEDs side by side.
Troubleshooting: When New Lights Still Don’t Work
You installed everything correctly, but the lights won’t turn on. Don’t panic. Here’s the diagnostic order.
Check the bulb first (if replaceable). Even new bulbs can be dead. Swap with a known working bulb.
Check polarity (LED only). Reverse the wires. Many owners install LEDs, they don’t work, and they assume the light is defective. Nope — just backwards.
Check the fuse. Your navigation light circuit has a fuse in your boat’s fuse panel. Find it. Test it. Replace if blown.
Check the switch. Switches fail. Use a multimeter to see if power is reaching the switch. If not, work backwards toward the battery. If yes, work forward toward the lights.
Check the ground. More navigation light failures are caused by bad grounds than by bad lights. Find where the ground wire connects to the boat’s common ground. Clean that connection. Scrape away any corrosion until you see shiny metal.
Check for voltage drop. With the lights on, measure voltage at the light fixture. If it’s below 11 volts, you have a wiring problem — too much resistance somewhere between the battery and the light.
What’s the most common failure after replacement? Loose connections and bad grounds. Go back and double-check every connection before assuming the new light is defective.
Maintenance That Keeps Navigation Lights Working
Navigation lights shouldn’t be “set and forget.” A few minutes of annual maintenance prevents failure on the water.
Annual checklist:
Check the lenses. Are they hazy, yellowed, or cracked? UV exposure damages plastic lenses over time. Replace the fixture if the lens is compromised — new bulbs behind a cloudy lens don’t help.
Clean the contacts. Inside the stern light socket, clean both the base contact and the spring contact with electrical contact cleaner or a small piece of sandpaper.
Inspect the gaskets. If your lights have rubber gaskets or O-rings (stern light pole, some pods), make sure they’re intact. A failed gasket lets water into the light and ruins everything.
Test at the dock. Before your first night trip of the season, turn on your navigation lights and walk around the boat. Can you see red, green, and white from all required angles?
Carry a spare stern light bulb. Stern light bulbs burn out more often than bow lights because they’re removed and reinstalled frequently. A $5 spare in your glove box saves the night.
When did you last test your navigation lights at night? Testing in your driveway doesn’t count — you need to see them in actual darkness to spot dim bulbs.

Light Output Comparison Chart
This chart compares incandescent vs. LED navigation light performance across key metrics.
How to read this chart: LED lights dramatically outperform incandescent in power draw (using far less electricity), lifespan (lasting 5x longer), corrosion resistance (sealed electronics), and heat output (running cool). The trade-off? None, really — LED is better in every measurable way.
FAQ: Navigation Light Replacement Questions Answered
What makes Avalon pontoon boats different for navigation light replacement?
Avalon uses model-specific integrated bow panels on many models — measure your cutout (typically 16.5″ wide) before ordering a replacement .
Do I need to replace both port and starboard lights at the same time?
Not strictly required, but recommended — especially if switching from incandescent to LED, as the brightness and color temperature will be mismatched.
Are LED navigation lights legal?
Yes — as long as they are USCG certified and meet visibility requirements. Many modern Avalons come with LED navigation lights from the factory .
How do I know what size integrated bow panel I need?
Measure your existing panel’s cutout width and height. Avalon panels typically require a 16.5″ wide by 5.125″ high cutout .
Why does my stern light keep burning out?
Check the socket for corrosion. Also, the bulb may be vibrating excessively — make sure the pole fits snugly and the base is tight.
Can I just replace the bulb instead of the whole fixture?
Sometimes — if the housing is in good condition and the fixture design allows bulb replacement. But many integrated LED panels are sealed units requiring full replacement.
How often should I test my navigation lights?
Test at the dock before every night trip. For daytime-only boaters, test monthly during the season.
Your Navigation Light Action Plan
Here’s what to do this week:
- Inspect your current lights — are both sides working? Is the stern light bright?
- Identify your light type — integrated panel or separate pods?
- Decide on LED upgrade — if your lights are more than 5 years old, go LED
- Order USCG certified replacements — not random Amazon lights
- Gather tools — including dielectric grease and heat shrink
- Schedule the replacement — allow 1-2 hours
- Test at night — from the water, not the dock
Safety reminder: Navigation lights are legally required equipment. Operating your boat after sunset without proper lights is illegal and dangerous. Always carry spare bulbs for your stern light.
The difference between old dim lights and new bright LEDs is night and day — literally. You’ll feel more confident. Other boaters will see you sooner. And you might just discover that night boating is the most peaceful way to enjoy your Avalon.
