Features to know about

Better Visibility on the Road: Dual Amber and Red LEDs

This pre-wired LED clearance light assembly mounts right on the fender to clearly mark the widest point of your trailer. The amber LED faces forward and the red LED faces rear, giving you visibility from both directions. Each light uses long-lasting LEDs that run brighter and more efficiently than old-style bulbs, drawing only 0.047 amps at 12.8 volts. There are no filaments to break or bulbs to replace—just steady light every time you hook up.

Built to Handle Wet Conditions: Sealed, Waterproof Design

Water damage is no threat here. The polycarbonate lenses are sealed to keep out moisture, making the entire assembly waterproof and safe for use on trailers that see rain or road spray. It’s a dependable setup you can count on whether you’re driving through a storm or washing down your trailer after a trip.

Simple, Durable Mounting: ABS Housing with Two-Wire Setup

The assembly’s ABS plastic bracket and housing mount securely on top or the side of your right fender without hassle. It’s designed for easy wiring with a basic two-wire setup—a ground wire and a lead wire for power—so installation stays straightforward. Housing dimensions measure 1-5/8" wide x 4-3/4" long x 1-1/4" tall, compact enough to fit cleanly while staying visible.

DOT Compliant for Peace of Mind: Meets FMVSS 108 and CMVSS Standards

You won’t have to worry about compliance when using this light. It’s Department of Transportation compliant and meets both FMVSS 108 and CMVSS requirements for automotive lighting. That means it’s approved for marking trailers over 80" wide, keeping you visible and legal wherever you travel.

Long Life Reliability: Backed by a Solid Warranty

The LEDs come with a lifetime warranty, while the housing and wiring carry a 3-year warranty. It’s built to last through years of use without fading or failing, giving you confidence every time your lights come on.

Hey Craig! I am sorry to hear about this. We will be reaching out to you.



by:

Easy install, good fit. Very sharp crisp lights. Easy to see for the size lenses both day and night.



by:

Perfect replacement. Easily ordering process, fast shipping



by:

Fit well on trailer. Good visibility. Would like it to have a longer tube so it would get a bit further out on fender.



by:

Nice product, exact replacement option for my trailer.



by:

Very bright and work great! Excellent upgrade for a 2009 CargoMate Blazer 6 x 12.



by:

This is the light for TrailersPlus 6x10 single axle fender



by:

Nice bright lights. Black is positive and white is negative. The packaging didn’t specify the polarity. With incandescent bulbs the lead connections don’t matter, but these LEDs won’t light up if connected backwards.



by:

I have ordered several products for the re-wiring and updating of by 10000 lb sailboat trailer. I have ordered electric brake kits, wire terminal boxes, led lights, etc. The shipping is incredible and fast, and the products are well made.



by:

The lights I received were just as shown on their website. I have NOT installed the lights yet, but the mounting, and wiring appears very straight forward. The shipping was very fast, as was the filling of the order. The company seems very service and customer oriented, even sending a note when they received word that my package had been delivered to me. I plan to send a picture or two along, once the lights are mounted, and working.



by:

The clearance lights work very well on my boat trailer.
I felt like the trailer needed a little more visibility and these Lights did the trick. Would recommend etrailer anytime products of this type are needed.



by:

Fast shipping on this product, easy to install the lights,used the trailor at night and the lights on the fender were bright and beutifull,didnt take a picture of the old lights on the trailor they didn't work half the time anyway.

by:
