This Peterson combination trailer tail light keeps things simple with a single square housing that handles six key functions—stop, turn, tail, rear reflex, side reflex, and side marker. Measuring 4-3/4" tall x 4-1/2" wide x 2-13/16" thick, it’s designed for trailers under 80" wide. Built-in rear and side reflex reflectors mean you don’t need separate reflector pieces, and its red lens over the incandescent bulbs delivers clear, visible signals that meet DOT standards.
Mounting this light doesn’t require complicated wiring or extra brackets. It installs using the included 1/4" studs spaced 2" apart (center on center) and grounds through its mounting hardware—no extra ground wire needed. Quick-connect wire inserts make push-in connections straightforward, helping you get a strong signal to every function without fussing over loose terminals or corroded contacts.
The molded housing and screw-on red lens are made to handle vibration and road wear without cracking or losing their seal. Inside are two easy-to-replace incandescent bulbs—an 1157 for the stop/tail circuit and an 1156 for the turn signal. If a bulb ever burns out, just remove the screws, swap in a new one, and you’re back on the road with full brightness.
Designed for standard 12V DC systems, this light draws 2.2 amps at 12.8V to keep signals bright without overloading your wiring. Everything about it is built for reliable performance across your brake, turn, and running light circuits so other drivers can see exactly what you’re doing day or night.
If you’re replacing an older trailer light, this unit lines up perfectly with common models—it’s a direct replacement for Grote #50542, Truck Lite #535D and #80322R, and Optronics #ST8RB. That means no drilling new holes or adapting mounts—just bolt it on, plug it in, and restore your trailer lighting the right way.

I can explain what's going on there. The shipping method chosen uses both UPS and your local post office. UPS takes the first leg of the trip, from our warehouse to your local post office. On arrival, it's marked as delivered. Then, the post office delivers it to you. This is why the tracking info lists the order as being delivered, but you haven't received it yet. I hope that helps! You should receive your order shortly.

Work fine- best configuration is to put lights on the boats trailer guide posts- keep the out of water. I store them inside when boat is not used!

No complaints at all. Thanks George for checking with me after a year. This was a surprise! As in my feedback a year ago, where I said you were like family, I still mean that. However, I think you forgot to let me know where the family was having Christmas Diner, last year. Thanks again.

Not much wire needs to be stripped in order to install. If you do not wish to watch this entire review video, the install and stripping start around the 2:10 mark:

The wiring harness is sold separately. If your trailer is 25 feet long or shorter, the # A25W42B would be ideal!

Still working with no problems. This trailer gets plenty of use besides going to the county dump, hauling landscaping material & lumber.
