Features to know about

Modern Look and Reliable Brightness: GloLight Solid LED Pattern

Older trailer lights can look patchy or uneven. This GloLight LED tail light fixes that with its solid, smooth pattern that gives off an even glow instead of the dotted look of typical LEDs. The outer bands of LEDs function as the tail light, while the center LEDs handle the stop and turn signals, so everything stands out clearly. With 28 diodes total, it’s bright, efficient, and easy to see in daylight or at night—all while keeping power use low at just 0.252 amps for stop/turn and 0.135 amps for tail at 12.8 volts.

Dealing With Water Exposure: Fully Sealed and Submersible

If your trailer ever hits wet roads or the boat ramp, this light is built for it. The sealed, waterproof construction keeps moisture out so the circuitry and diodes stay protected. It’s specifically designed for trailers that may be submerged, which means no worrying about leaking housings or corroded wiring after a launch. Once it’s mounted, it’s ready to handle water without missing a beat.

Durability for Rough Roads: Shock-Resistant SMT Build

Vibration can ruin fragile bulbs over time, but this light uses surface-mount technology (SMT) to keep its LED circuit board strong and stable. That design helps it withstand bumps and shocks better while improving heat distribution for longer life. You don’t have to deal with brittle filaments or frequent bulb replacements—just consistent lighting that lasts up to 50 times longer than incandescents.

Simple Mounting and Wiring: Straightforward Setup That Fits Right

Installing this passenger-side light is easy with its surface-mount design—no hole cutting needed. It mounts flat with included studs spaced 2 inches apart on center, making positioning simple. A 3-wire pigtail handles the connections: white for ground, brown for tail, and green for stop/turn. That’s all you need to get a reliable connection that’s ready to go once sealed up with weatherproof connectors.

Safe Coverage and Compliance: P2-Rated and DOT Approved

Safety and visibility go hand in hand. This light meets FMVSS 108 and CMVSS 108 standards for automotive lighting and carries a P2 rating that provides a 45-degree spread of light to either side for clear coverage from the rear. It also serves six functions in one—stop, tail, turn, side marker, side reflex reflector, and rear reflex reflector—keeping your trailer compliant and visible in every condition.

Looks to be a well built light. Everything proved to make a hookup quick and easy!!



by:

Very nice product. Could have come with wiring diagram instead of going back on my computer but thats ok. Would have been easy to label at least the colored lines - White is obvious.



by:

very dim



by:

Awesome lights! Well made, easy to install, and they look great.



by:

The light works extremely well. It is very bright and the stop portion of the light is fantastic! Very obvious to drivers behind me. The only reason I bought only this one as I had a trailer tire blow and it took out my fender and light. I bought this one to replace it.



by:

Half of the LEDs are already inoperativ e.

by:

I installed the lights at full sun. And they are still bright.



by:

Look great really bright, hoping they stand up to being waterproof/submersible.



by:

Great lights. Fits my Ranger Trail great and light up very bright !



by:

exactly the replacement I needed for my boat trailer



by:

Great light! Installed easy, very bright and can be seen easily in the bright sunlight. Go easy on tightening the nuts as the only thing to keep the bolt in the light from turning is plastic.



by:

Very good product, I will recommend this light to anyone who wants to upgrade a boat trailer.



by:

I replaced my broken trailer light using etrailer.com service was great and the replacement product high quality.



by:

Terrific product.......if you are tired of dim incandescent taillights this is the answer. Very, very bright in the full sunlight...even brighter for turn & brake function. There is no excuse for anyone to confuse your intentions of braking, turning or emergency situations. Simple two wire per side butt connection.



by:

These lights are bright and are very visible ... love the new look on my boat trailer!!

Love these tail lights .. nothing short of amazing and crazy bright!! Lots of compliments on them .... and still working on my boat trailer after submerging each weekend at the boat launch.



by:

I have bought about 5 of these lights for my boat trailer (I have broken a few. Every time it was my fault). The lights look great and work well. Really helped clean up the look of my trailer.



by:

Previous review was subject to troubleshooting why the lights weren't working.

Problem was in the plug between the truck and the boat.

The lights are fine and I'm upgrading my initial review from good to excellent. I really like the overall look and the bright light the LEDs provide.



by:

Because one my boat trailer stop/tail lights was damaged I decide to upgrade both of them from incandescent to LED. What a difference; downright dazzling! The change out was as simple as could be given that the format and wiring of the lens/lamp housing was virtually identical between old and new. So much so, in fact, that I kept the undamaged old lens and housing to use in case of an incident enroute.
NOTE: I didn't use the crimped-on eye connector to ground the assembly to the mounting bolt of the housing as provided. I cut the eye off and wired directly to the coupler ground having just added a "car end" 6-pin to the boat trailer. Yes, I hate trailer lights that much!



by:

Fits perfect no problem
