Features to know about

Brighter, Longer-Lasting, and Efficient: LED Clearance Light Assembly

This LED fender light assembly gives you the visibility you need without the hassle of swapping out bulbs. The sealed amber and red LEDs mark the widest point of your trailer—amber facing forward and red to the rear—for easy identification on the road. The LEDs last longer than incandescent bulbs and draw less power, only 0.047 amps at 12.8 volts. That means more brightness with less energy use and no fragile filaments to worry about.

Reliable Marking for Wide Trailers: Designed for Over 80" Widths

When your trailer is over 80" wide, marking the outer edges is more than a good idea—it’s required. This pre-wired light assembly mounts right on the left fender to clearly define your trailer’s width from both directions. It meets FMVSS 108 and CMVSS standards, so you’ll stay compliant while adding a clear visual cue for other drivers. The compact housing measures 4-3/4" long by 1-5/8" wide by 1-1/4" tall, fitting neatly while still standing out where it matters most.

Water and Weather Protection: Sealed, Submersible Construction

Rain, spray, or even full submersion won’t faze this light. Its polycarbonate lenses are sealed to keep moisture out completely, protecting the LEDs from corrosion or short circuits. Whether you’re driving through heavy rain or backing down a ramp, the waterproof build keeps the internals dry and working strong season after season.

Simple DIY Mounting: Pre-Wired and Ready to Go

Getting this light installed is straightforward thanks to its pre-wired design and durable ABS plastic housing. A built-in ground wire and lead wire for power make hookup simple—no rewiring or complex setup needed. Just mount it with your chosen screws (not included) and connect the two wires. Once it’s in place, you’ve got a dependable clearance marker that’s built to last, backed by a lifetime warranty on the LEDs and a 3-year warranty on the housing and wiring.

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:

Installed driver and passenger side LED marker lights on my enclosed work trailer. Was looking for an OEM replacement, and these were extremely close to the originals. Very happy with etrailer.com and great packaging & fast shipping.



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. Also put new tail lights on very bright, Will buy from them again have another one to do. THANKS again etrailer great product!!!!!



by:

The compact size made it easy to locate on the fender. I added a grommet for extra protection going through a metal fender.



by:

There very bright and I’ve had no problems with them.



by:

Nice light... this was the second set I bought.

Do be careful when ordering, they come in sets of two LEFTS or two RIGHTS, not a set of ONE LEFT & ONE RIGHT



by:

Easy upgrade from incandescent bulbs to LED. Extra wire length lets you adapt to older trailer installs



by:

Extremely bright and easy to install. Highly recommend. Only drawback is they do not come with mounting bolts/screws. Would buy again



by:

Nice lights, a bit over priced but work well.
I have them mounted on my trailer so I can see the end of the trailer in both mirrors when traveling straight.
