For trailers that see water, this 2-1/2" round Optronics light is built to stay sealed and working. The housing and red lens are sonically fused into a single waterproof unit, making it fully submersible and safe from moisture getting inside. That means you can use it confidently on wet roads or even when your trailer goes underwater without worrying about leaks or short circuits.
Good visibility matters every time you’re on the road, and this light delivers a bright signal that meets DOT P2 standards. The beam pattern covers 45 degrees to either side of centerline for 90 degrees total, giving plenty of light straight-on for clearance or side marker use. It’s simple too—a replaceable incandescent bulb behind a red snap-on lens that keeps maintenance easy and visibility consistent.
Instead of juggling separate parts, this light integrates a reflex reflector directly into the lens. That built-in design saves mounting space and meets safety requirements without additional hardware. It’s a clean, practical setup that keeps your trailer visible even when the lights aren’t on.
Installing this light is uncomplicated and adaptable. It fits in a recessed mount using a grommet (A55GB or A56GB—sold separately) and connects through an industry-standard 2-prong plug such as the A46PB or A86PB. Once mounted, the open back design allows for easy wiring access, so setup stays quick and tidy.
A tough polycarbonate housing protects the incandescent bulb while drawing just 0.2 amps at 12.8V. At only 11/16" thick, it sits tight against the surface yet handles vibration and weather without issue. With its 3-year warranty and proven cross-reference fit with Uni Bond #SR2500R, Wesbar #223224, Truck Lite #10205R, Grote #45812, and Peterson #143R, it’s a dependable choice for reliable trailer lighting that lasts.

Got exactly what I ordered. Fast shipping. Good price. Everything as expected and it works great!
Marker lights are exactly what i needed.Vary timely shipping.
I've ordered a number of parts from etrailer over the years and everything came on time and was correct it's a joy to do business with them they're very good at getting the correct part the first time
Comes with already some connector grease on the connectors, which is really nice. Worked perfectly, just connected and they lit up. These are great and the measurements are accurate. They fit J-20 as well.
The light was just right. It fit in the opening on the trailer and worked as soon it connected to the power.
Items were as described, fast shipping and thank you Matt for your assistance
The lights are fine but the 2 1/2" grommets are too small for PJ trailers. Had to reuse the old ones.
Equal to or better than the same lights available locally, but at half to 1/3 of the local prices. Even paying shipping I save a lot. Delivery with E-Trailer is always timely, too.
I replace the clearance lights on my motorhome and these fit perfectly
fit in existing bezel fine. nice and bright. Rec'd quickly. if I had of installed the day I rec'd, I would not have had discussion with iowa trooper. my bad, could have been prevented as your service shipping was spot on
Replacement lights for my trailer were exactly what I needed and ordered. Arrived promptly in excellent new conditions. Have used etrailer before with same excellent results and will use them again. I'm very satisfied.
Perfect match 2022 Bounder
So fast to ship
Great service
I completely rebuilt my boat trailer and used a lot of parts from e trailer
Every part was of great quality. Very good prices and fast shipping. I would
use them again for all my trailer needs.
I have a flat bed on my truck and it uses trailer lights in it. When I looked for replacements all the stores wanted $10 to $30 a peace!!! Etrailer saved me almost $100 over going to may local store. I ordered it on sunday night. I had 2 personal emails telling me my order was ready and being shipped. ON SUNDAY NIGHT!!! I had my order by Wednesday with a follow up email telling me my package was waiting for me at home. My only complaint is why other online stores can provide this service. etrailer, I will be ordering again. Thank You
Exactly as shown. Fit perfect. The order was shipped fast and was correct.
Exact replacement for the side marker lights on my boat trailer.
Just what I need for my motorhome. Arrived much sooner than I expected. Installation was a snap.
