Features to know about

Better Visibility with Efficient LEDs: Bright, Low-Power Light

Switching to LEDs means more light with less power draw. This Optronics ThinLine light uses 3 white LEDs behind an amber lens to produce a bright and efficient output while only drawing 0.048 amps at 12.8V. It lasts up to 50 times longer than incandescent bulbs, so you won’t have to worry about replacing burned-out filaments or dealing with dim lights again. It’s a simple upgrade that boosts safety and reliability every time you hit the road.

Fighting Water Damage: Fully Submersible and Sonically Sealed

Water intrusion ruins lights fast, but this one is built to take it. The polycarbonate housing and lens are sonically sealed into one waterproof unit that keeps out water and moisture completely. Whether it’s rain, washdowns, or even submersion, the LEDs stay protected from corrosion and shorts. That sealed design means you can count on the light to keep working, season after season.

Tight Space Installations: Low-Profile Surface Mount Design

Sometimes space is limited, but this ThinLine Series light fits right in. Measuring only 4-1/8" long x 1-1/4" tall x 1-3/16" deep, it mounts flat with the included chrome bracket and uses a single wire that grounds through the mounting hardware. The low-profile design looks clean and stays out of the way while still giving you full P2-rated visibility coverage.

Reliable Beam Coverage: P2-Rated for Targeted Illumination

This light is P2-rated, producing a 45-degree beam on each side of its centerline for a total of 90 degrees of coverage. That makes it ideal as either a clearance or side marker light when mounted properly. It’s DOT compliant too, so you’ll stay visible and on the right side of lighting regulations.

Built to Last: Durable Polycarbonate Construction

From road grit to constant vibration, this light holds up under tough conditions. The polycarbonate housing and lens resist cracking, fading, and impact damage. With its lifetime LED warranty and rugged build, it’s a dependable option that keeps shining bright without extra maintenance or replacement hassle.

Wow, what a difference LED clearance lights make, especially at night. It makes my business information really stand out and people who follow me really notice that. I've been wanting to go LED the past couple years and now that I recently made the change, I'm not ever going back to standard low-level light bulbs again. Thanks etrailer for offering these lights and at a very affordable price. You were almost half the price as our local part store was selling them for, plus these are more stylish as well.

Boat Trailer: Following a highly successful conversion of the brake/tail & DOT lights, I went ahead with changing the amber running/side maker lights. Working with Hally made ordering smooth and simple. The parts arrived via USPS as expected in excellent condition.
The new LEDs fit perfectly into the OEM housing, so I chose not to change them at this time. THe difference in illumination is just outstanding!!!
I will definitely use eTrailer again with two great experiences on this project.
Seeing the outcome, I cannot explain why it took me so long to decide to convert.



by:

Perfect replacement for older Shorelander fender marker light. The connections are more near center than end to help fit wires.



by:

There was only one power base in the package with two plug in amber lenses. I had to call customer service to get a second power base shipped out.



by:

great fit

Was hoping to rivet base to fenders, cheap plastic might not hold up to rivet pressure



by:

Description should say Chrome plated a 'plastic' bracket



by:

Was what I wanted



by:

These lights are not well made. I Cracked one base while riveting it onto my trailer, And cracked a second one when I accidentally installed a red marker where a yellow belongs.- don’t try to remove the lens once clicked into place. They light up, but that’s as much positive as I can give
