This 3-3/4" round Peterson tail light keeps things simple and dependable. It handles four functions—stop, tail, turn, and license plate lighting—so you get all the signals you need in one housing. The built-in license plate light illuminates the plate clearly without needing a second fixture. It’s DOT compliant and designed for 12V DC systems, drawing 2.2 amps at 12.8V through a single 1157 bulb that’s easy to replace when needed.
Mounting this light is about as easy as it gets. Two 1/4" studs are fixed on the back with a 2" center-to-center spacing, so it bolts right onto flat metal surfaces without extra brackets or drilling odd holes. The ground is built into the hardware—just tighten it down to bare metal and you’re done. A 10" two-wire lead handles power for running lights and stop/turn circuits, making wiring clear and quick.
Made with a tough polycarbonate body and a red wrap-over lens that screws on securely, this light holds up well against road wear and vibration. The materials resist cracking and fading over time, and if the lens ever gets damaged, replacements are readily available. This design makes long-term maintenance simple without replacing the entire assembly.
For those who like a traditional look, this round light keeps that familiar style while staying practical. At 3-3/4" in diameter and 2-5/8" thick, it fits cleanly on most trailer panels without sticking out awkwardly. The incandescent glow is bright and easy to spot from behind—perfect for keeping your trailer visible day or night while maintaining that classic trailer-light appearance.

Ratings & Reviews
The tail lights are replacements for ones that rusted. They are not installed, but the stud pattern and size are exactly as described and fit the light bracket very well. The tag bracket only needs slight modification to attach to the left tail light bracket. The parts are satisfactory for my needs. Thanks.
This trailer has been a real pain. Hard to find bearings and seals were nearly impossible The lighting enclosures border on stupid. I really appreciate you guys going the extra mile. You got my business. Thanks, Joe in Bend Oregon
Having an older trailer, it was important to find a newer match for the trailer tail lights. These were just the thing I was looing for and at the right price with shipping.
this is an inexpensive light that was originally used on pull behind trailers. It is smaller OD than usual, because people used tom put them inside steel pipe to protect them. With the advent of low profile leds, this lights usage has declined. etrailer has it in stock at a reasonable price and good quality. these lights are most often sold when someone wants to match their old style, or put back inside a steel pipe.
I purchased trailer lighting for my flatbed trailer. Very satisfied with the parts and the service I received. Will use you again when the need arises.
excellent service and product
I put this on a classic Holsclaw motorcycle trailer. I felt it was the closest representation of the lights that came with the trailer and this brand was recommended to me by an enthusiast group that loves these old trailers. I was very happy to see that etrailer carried this brand. Even though I live close to the warehouse, I had these shipped and they arrived quickly. These are well made, durable and so far have worked flawlessly.
The products were acceptable quality and the customer service was UNEQUALED, EXEMPLARY, GREAT, etc.
The trailer overhaul job went well and we hauled a capacity load almost 1500 miles in some difficult road conditions, stopping only for fuel and to sleep.
We'll use your products again.
There work great! I used them to require and older sailboat trailer that has two license plate lights, one for the plate, the other to illuminate to boat to not startle people at night.
Would have helped having wiring directions, lights had black and red wires, didn't match the wiring harness
I got the round 431800 & 432000 for a 4x6 ft trailer. I had to mount them at 90 degrees from horizontal in order to light the license plate. The 432000 is designed for the license plate to be under the light. I sent an email to etrailer asking if they would let rain water in when mounted this way. They responded in about a week & said they would be fine. Well, they are not fine. Both will let rain water in when mounted this way as the drain hole is now on the side instead of bottom! I tried to caulk the holes, but caulk does not stick to the plastic. I used tape inside the housing with caulk sticking to it. Not sure how well that will work. I drilled new drain holes in the bottom. I replaced the lens screws with SS ones. I kept these only because I could not find anyone else selling them. They work, but my old ones had the clear lens welded to the housing and could be mounted anyway. These are cheap and the clear lens is snapped in with lots of gaps for water to come in. Not real happy with the results.
Broke the factory taillights on my 2003 Kawasaki Mule. They are 90 plus bucks each from Kawasaki...Ouch! I bought two of these and they were shipped all for under xx bucks! They fit perfectly, do what they are intended for and look great on my mule. Thanks E Trailer!

The lights are working just fine. Great product.
Very pleased. Easy installation. The lights are bright with good reflectors and side marker lights and the price can't be beat.

I made an excellent choice. Everything works well and has resisted the elements well. Very happy with this.
The lights came in a very timely fashion. They were well packed. I replaced my 1965 camper trailer tail lights and these fit just right. The price was very competitive and since I had good results in a previous order, I went with etrailer again.

Great follow up, Laura.The lights were just like the original ones on my trailer. Installed easily and worked the first try. I wanted to keep my 1965 Bethany camper as original as possible and these lights did the job.
Would like in led and wires could be longer make insulation easier.
Couldn’t tell from the photos if they were waterproof for a boat trailer. Would be good for landscape or construction trailer but can not be submerged
Very well made
Great experience
Needed a quality light that I could use on a motorcycle bobber build; and this fit the project perfectly.
Thank You for your excellent service.
Lights were exact replacement and just what I needed. Your website detail was helpful with installation.
Our old lights in the back of the 1976 Ford F100 wore out. These are almost a match. I couldn’t find any without the clear lens for license plate. Covered the lens with black tape. All good. Thanks. Great service fast delivery.
The product came 3 days later then I was originally informed it would be received. The housing for the light was plastic rather than metal. It did have the mounting hardware. I was able to get it installed and it is working.

Its been a year after installation in all kinds of travel weather and just to light is still working perfectly. I would recommend it to anyone in need.
Received the lights on the day they were supposed to be delivered. The dimensions were as described on the website so they fit perfectly. Wired them up and now good to go!

I'm sorry about that, it sounds very frustrating! The black wire carries the running light circuit and the red wire carries the stop and turn signal.
