Old incandescent lights can be dim, fragile, and power-hungry. This thinline LED fender light uses two powerful diodes that shine bright with less draw—just 0.048 amps at 12.8V. The amber lens faces forward and the red lens faces rear, keeping both directions clearly visible. Because it’s all solid-state, there are no filaments to burn out, and the LEDs last up to 50 times longer than old bulbs. You get a brighter, cleaner glow with less power wasted.
Water damage is the enemy of trailer lights, but this one is built to take it on. The red and amber polycarbonate lens and housing are sonically sealed into a single waterproof piece. That means it’s fully submersible—perfect for trailers that see water or constant road spray. The sealed body keeps moisture away from the diodes and circuit board so this light stays reliable season after season.
Space can be tight along a trailer fender, which is why the Thinline Series design works so well. At only 3-7/8" long, 1-1/4" wide, and 7/8" thick, it tucks neatly onto the fender without sticking out or catching gear. The surface-mount setup uses bracket A65B (sold separately) and fits standard 1-prong or 2-prong plugs like A65P, making installation simple and clean without extra drilling or wiring headaches.
Visibility from the right angle matters for safety. This light carries a P2 rating, producing a 45-degree beam to either side for a total of 90 degrees of coverage. It works well as either a clearance light or side marker light depending on where you need visibility most. Paired with its durable housing and long-life LEDs backed by a lifetime warranty, it’s a simple, dependable lighting solution that just works.

Great build quality.
Perfect plug in replacement for my snowmobile trailer fenders
Exactly as advertised. Fit like a glove and works like a charm. That's all you can ask from a trailer light.
Had a heck of a time finding a replacement marker light for my new trailer! (Lost it in Chicago?) Fortunately found the exact replacement at etrailer! Way to go etrailer!
Received package in a good amount of time. I put it on my 4x8 trailer. It snapped in as it should. It works well. I had ordered two just Incase the other light went out. I will order from you again.
It is an exact replacement for my trailer. I was glad to see that the light does not have the etrailer stamp on it like is shown in your pictures. I couldn't find this light anywhere locally. I was glad to find it on your website. Thanks!
Haven't used yet but look identical to what's on my trailer currently
The lights worked out perfectly. Still bright as ever! Thanks etrailer for a great product & fast shipping.
Trailer side marker amber/red .... 2 prong plug in .....

Exact replacement
We have a 7x14 low rider trailer and replaced all lights and marker lights with LED lights. The figment was perfect and they look much better than original lights.
Perfect retro fit for the old incandescent bulbs. Snaps right into place using the old mounting hardware. No problems with the new LED's. Always work and very bright.
It is an exact match to the fender running lights I currently have on my horse trailer. This was the only site that I was able to find them.

Still working perfectly!
Works well
This is exactly what I n eeded.
Worked great
Really like these lights but by choice I have them where they take a beating sometimes. Even though I have to replace them on occasions it’s worth it to me. Actually they are really rugged, I’m extremely happy with them. Etrailer is my go to place for any trailer part!
Excellent replacement for my incandescent fender lights. These actually sit a little more proud than the old lights and look really great! I've been an eTrailer customer for 15 years and they have all the products, with excellent service! Shout out to Will, who helped me with several orders!
Product was delivered promptly and as promised, and the picture/description matched exactly what I ordered/received. Very happy with my purchase and their inventory, and would definitely conduct business with this company again - no question. 5 Stars!
100 out of 100
fast shipping, great communication and the product matched the description
The lights look identical to the original. Have not tried to install the one yet, but will as soon as I can. Thanks.
This led light is superior to any I have seen. The new lights made my 20 year old horse trailer look like new going down the road. Being visible is important to us and our livestock.
These fender lights are perfect replacement for my Aluma trailer! I had a cracked one so I bought two so they’re both new awesome product. Trailer always has the perfect parts or replacements I need for my numerous trailers. Thanks!
Exactly what I ordered, and ahead of expected delivery date. Thank you.!

You're very welcome, Dave! Glad we could help! : ) Looks good on there too. What are you typically towing?

No issues. Still works great after multiple launches and being completely submerged in water.
