This 5-1/2" round Peterson LED trailer tail light puts out a bright, clean red light for stop, turn, and tail functions—all while drawing only 0.13 amps at 12V. The single white diode shines through a red lens that keeps the classic incandescent look but with all the benefits of LED efficiency. It lasts up to 50 times longer than old-style bulbs and uses far less power, so there’s no worrying about burned-out filaments or dim lights.
Once this light is installed, you can forget about swapping bulbs. The solid-state LED design means there are no fragile filaments to break and no sockets to corrode. It’s built for long-term reliability and consistent output every time you hit the brakes or turn signals.
The light mounts flush to the trailer surface using its built-in gray flange for a neat, finished appearance. It fits into a 4-1/2" round hole and locks into place with secure tabs. This setup keeps the housing tight and stable while still looking clean and professional once mounted.
Hookup is simple thanks to its compatibility with an industry standard 3-prong plug (431-491 sold separately). The plug clicks in with locking tabs that hold a solid connection even on rough roads. You get a secure, dependable link without cutting or splicing wires—just plug in and go.
Whether your electrical system runs at 9V or up to 16V, this light is built to handle it smoothly. That means steady brightness and full function across normal vehicle voltage ranges, keeping your signaling clear and consistent in any condition.

Today, we're going to take a look at the Peterson round, LED stop, turn, and taillight with the gray flange. Now, this is a red, round trailer light that serves three functions on the trailers. Offers a stoplight, taillight, and a turn signal light, and it uses LEDs, which will make great replacements for incandescent lights, 'cause the LEDs will last about 50 times longer. They're more efficient, provide brighter light with less power output. And of course, no bulbs to replace, no brittle filaments. It's a red lens over white LEDs.
I had mentioned it has the gray flange to it, and it mounts on the trailer with this builtin flange.Now, the hardware to mount it, you see the three holes here, that is not included. Now, it does require a four and a half inch diameter round hole for installation. It is designed to accept the industry standard three-prong plug, which we do sell separately. It's part number 431-491, and it's listed on this product page as a related product.This light is made in the USA. The specs on this, the power draw at 12V is 0.13 amps.
Operating voltage is 9V to 16V. The LEDs do have a limited lifetime warranty. Few dimensions, and then I'm going to hook it up and show you what the functions are and how bright it is. Overall dimension from edge is edge is right at 5 1/2 inches. Total depth from the very front to the furthest part back is going to be right at about 1 11/16 inches deep.
The lens itself diameter is 4 1/4 inches. The mounting hole dimensions, in other words these holes here from center to center, it's going to be right at 4 1/4 inches.So what I'm going to do now is we're going to go ahead and plug this in. Here's that three-prong plug we talked about, and it'll plug right into the back. Once you get the holes lined up, just go ahead and plug it in. Now that we got it plugged in, I'm going to go ahead and hook up our connections.
Once we get it hooked up, I'll go ahead and turn off the overhead lights. There we go. Got it all hooked up. There you can see the taillight function. Let me go ahead and turn off the overhead lights. Then you'll be able to see the brake function. So when you apply your brakes, you'll get a brighter light. When you turn on your turn signals, you can see, then you get your turn signal function. Very bright light using LEDs. Going to go ahead and turn back on our overhead lights, turn off our power.But that should do it for the review on the Peterson round LED stop, turn, and taillight with the gray flange.

Ratings & Reviews
They look like they will do the trick. Wish they would have come with the simple wiring.
Good light, not what I needed and was very easy to return.
great products and lightning fast shipp ing
The product probably was correct and looks like it was quality made
The problem is, it has a 3 prong electrical connector, which I didn't have
on my (old light), so I need to talk to you Monday to have you verify which
additional connector product will match up to it. This will be following my
up on making sure it will fit on my trailer first, which I think it will?
I do have a problem with getting a couple of parts at $2 to $3 each and paying the additional around $10 shipping. If I knew I need them, I could have got them with the original order, wasn't told about that connector?
