Features to know about

Reliable Lighting on the Road: Bright, Efficient LED Design

This 2" round Optronics light uses three white LEDs behind an amber lens to give you bright visibility with very little power draw. At 12.8V it only uses 0.06 amps, so it’s easy on your wiring and battery while still giving off a strong, clean light. LEDs last up to 50 times longer than regular bulbs and don’t have fragile filaments to worry about. Once it’s in place, you won’t be swapping out burned-out bulbs again.

Keeping Moisture Out: Sonically Sealed and Submersible

Water is tough on lights, but this one’s built to handle it. The polycarbonate housing and lens are sonically sealed into a single waterproof unit, keeping the inside completely dry even when submerged. It’s ideal for wet or muddy conditions where other lights might leak or fog up. The sealed design protects the diodes and circuit board so the light stays bright and dependable.

Straightforward Mounting: Recessed Fit with Standard Plug

Installing this light is simple thanks to its recessed mount and standard 2-prong connection. It fits neatly into a 2-5/16" diameter mounting hole when used with the A54GB rubber grommet (sold separately). Just plug it in using an industry-standard pigtail and you’re ready to go. The clean, flush fit keeps it protected from bumps and scrapes while giving your setup a neat look.

Clear Visibility Where You Need It: P2-Rated Beam Pattern

The P2 rating means this light throws a focused 45-degree beam on each side of center for a total of 90 degrees of coverage—perfect for use as either a clearance light or a side marker light when properly mounted. It’s bright enough to be seen directly from behind or ahead, helping other drivers spot your trailer at night or in low-light conditions.

Built to Last: Durable Polycarbonate Construction

The amber lens and housing are made from impact-resistant polycarbonate that stands up to road debris and vibration. With long-life LEDs backed by a lifetime warranty, this light is made for years of reliable service wherever the road or water takes you.

The wiring pigtail is available separately as part # A46PB. We should have made that more clear in the product description, I'm sorry about that. We're having that updated as we speak.



by:

Everything fit perfectly, LEDS are the best. Great follow-up and communication w/ the shipment. I felt like my business actually mattered. Thanks



by:

I have been very happy with all the purchases I have made at etrailer parts arrive on time and our what I expect i’d like to thank you and your staff for the service I provide



by:

Great product and price and high speed delivery. Now if I only knew where the three tires and wheel were that I ordered from etrailer on the 21st were. And although showing in-stock on the order update document, they haven't shipped yet. Must be in the Bermuda Triangle.....



by:

a little more involved install then I was anticipating, the 2 wire pig tail doesn't fit in the space behind the grommet, so I had to use a hole saw and cut out a piece of the fiber glass roof, looks good



by:

Perfect fit. Works great.

by:

Easy installation, connections cam PRE die-electric greased which was a nice bonus!

I did buy new grommets with these as well.


Bright and should last a lifetime!



by:

The trailer lights from etrailer shipped fast and arrived comfortably packaged. They were a perfect replacement for my CAM Superline equipment trailers.



by:

Have not yet had time to install the LED lighting items I recently purchased to refurbish my car trailer.
I will say however that the customer service I experienced from etrailer was bar none the best I've ever encountered.
Items received were correct and expertly packaged as well.
Thank you for the great experience!



by:

Awesome product and great service.



by:

perfect fit and function



by:

Matched the original lights that were 15 years old and wore out. Connection and fit were perfect.



by:

Great product. Not only do these replacement marker lights give my auto trailer an updated, or modern look they also greatly enhance its visability to others on the road. This is a huge safety improvement. They were also a snap to install, approximately 2 minutes each including clean up of the wiring connectors. I love them.



by:

Purchased LED lights to re-wire a 12-year old trailer. etrailer had all the lights/gaskets needed. Perfect fit to the original OEM lights.



by:

Great product, easy to install as a replacement of the original marker lights.

Working great. Much brighter than the old ones.



by:

Excellent products. These lights work perfectly, are rugged and seem to last. The license plate lights are super bright so law enforcement have no problem reading the plate which avoids unnecessary stops. The lights are directs replacements as well so no modifications needed. Great products. I recommend etrailer to many of my friends and colleagues.



by:

The LED marker lights worked great and after a year still working fine



by:

Nice, bright and easy to install. A much needed upgrade from the incandescent bulbs. Makes my boat trailer look great!



by:

Just as described and expected.



by:

Work well and received quickly



by:

These are smaller in diameter than the originals, but I can make them work.



by:

Easy to install and works great!

@Pat Road salt can be brutal on lights, so it’s great to know they’ve held up that well over a couple of years without any issues. I really appreciate you sharing that kind of long term experience since that’s exactly what people are looking for when they’re deciding. What are you using the lights on?
