This 4-5/16" round Optronics light delivers all three functions—stop, turn, and tail—in one dependable unit. The red lens covers a single 2057 dual-intensity bulb that handles both bright brake signals and lower-intensity running light duty. It’s built for 12V DC systems and draws 2.5 amps for stop/turn and 1.0 amp for tail, giving you solid brightness and consistent visibility wherever you tow.
Rough roads and vibration can break weak bulbs, but this light’s shock-proof socket helps protect the filament from damage. The housing is made of durable plastic, and the red snap-on lens keeps everything secure without tools. You get a sturdy light that stands up to the bumps, ruts, and weather that come with regular trailer use.
Installation is quick thanks to the two included studs spaced 2" apart on center. The studs also act as the ground connection when mounted directly to a metal surface—no extra grounding wire needed in most setups. The 2-wire design keeps things simple: one lead for stop/turn, one for tail. If you’re mounting to something non-metallic, a quick jumper wire handles the ground.
When bulb replacement time comes around, it couldn’t be simpler. The snap-on lens pops off easily for access, and the common 2057 incandescent bulb swaps out in seconds. No need to replace the whole assembly—just change the bulb and you’re ready to go again.
If you’re replacing an older unit, this model lines up with existing holes and wiring from several standard lights. It’s a direct replacement for Uni Bond TL4402, Wesbar 3050, Truck Lite 80314R, Grote 50862, Peterson 428S, and Bargman 30-15-001. That means no drilling or adapter brackets—just mount it up, plug it in, and get back on the road.

This is a good, inexpensive light.
I'm not ready to move up to the LED type yet.
I only need 4 lights but why not have a couple of spares sitting on the shelf?
Thanks again,

Inexpensive, fit my old trailer exactly. One of the bulbs burnt out shortly after I began using, but other than that very good.
Great little lights. They are bright and seem to be well made. The price was great and the shipping was quick and i even had them shipped economy.
Worked great for my old trailer re wire project.
For the money, these work fine. Don't expect very a very durable product though. They are cheaply made, and looks like water can get in eventually. Fine for a rarely used trailer.
Wish i would have paid the extra and gotten the Metal Housing Tail Light. What i have is working well and should last.
Arrived in great condition and easy to replace. Could have gotten to me sooner, but I didn't pay for expedited shipping. Just spoiled on 2-Day Amazon Prime I guess.
Trailer lights are working fine, thanks for asking!
Just what I was looking for. Came to me very quickly and was kept informed of tracking. Also asked a question of their experts and was answered very promptly.
These were hard to find but etrailer had just what I needed with incredible shipping and customer service.
Great product and customer service. Pricing and shipping were awesome.
For the price you can' t the two tail lights I purchased. I received my order in a timely manner and am very satisfied. I will be recommending this company to my freinds.
Your product prices are great, shipping costs were very reasonable, and your service was excellent. I got exactly what I ordered.
Thanks!!
Exactly what I was looking for. Fits perfectly in the holes of my old trailer. Only place I can find the round tail lights.
Great people, had problem with my order, e-mail them, and they fixed it just a little long on shipping would buy from them again
Look nice and mounted easily. Only issue I had is the bulbs fit loosely in the socket, so they intermittently lose contact, causing them to burn out frequently. I tightened the sockets up by bending them with pliers and it seems better.
Delivery was very fast and the product is exactly as described. I've installed many trailer lights, but if someone new was ordering, it would have been nice to have some directions, like which color wire was for what!!
We purchased an old snowmobile trailer to adapt to a hauling trailer. The lights were long gone but the steel surrounds were still there. We were able to order the exact light fixtures that had been in the surrounds even with the right mounting bolts on the back.. Made for a quick clean installation.
These lights worked amazing and were built better than other lights similar in size.
Super fast shipping. Would use again. T hanks
well packed and quickly shipped
Worked great!
Great, simple tail lights. An exact replacement for what they used in 1970 when they homebuilt the trailer. I wanted something that would fit in the tubes to protect them from the heat of the firebox and damage. A perfect set to make the BBQ Pit road legal again.
I have not received them yet.
