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.

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.

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.
