Combination Lights for Trailers Over 80" Wide

Flatbed trailer over 80" wide with combination tail lights

If a trailer is 80" or wider at its widest point, then it requires rear clearance lights in addition to basic trailer lights. These clearance lights indicate the width of the trailer when it is viewed from the back.


To meet these requirements on a flatbed utility trailer where the bed extends past the wheels, you can install combination trailer lights that include the rear clearance function. For proper mounting, the lights must be installed at the widest points on the rear of the trailer - one on each corner.

Video Transcript for Optronics Trailer Lights - Tail Lights - ST2RB Review

Today, we're going to be reviewing part number ST2RB. This is the square trailer light for the right hand side of your trailer, from Optronics. The red square light is going to serve 7 functions for trailers more than 80 inches wide, such as your stop, turn, tail, rear clearance, rear reflex, side marker, and side reflex indicators. It's got a corrosion-resistant design featuring a replaceable lens, as well as replaceable incandescent bulbs. The bulbs are going to use a shock-proof socket, so it's going to guarantee a long bulb life. The stud mounts on the right side of the the trailer with 2 studs. It's inaudible 00:00:33 on the back of the housing. Taking a measurement, the distance between the two, center on center, is going to measure right around 2 inches. This is designed for quick-connect wiring.

You can see here at the top that it's got the exposed portion for the wiring. Wiring is going to be sold separately, or you can use your pre-existing wiring. All you have to do is simply insert the stripped wire into the holes for a secure connection. The light is going to ground through the connection points there on the studs. You can ground straight through that. It's got the nice star-shaped washer there on one side of the nut.

That way, it can get into the surface really well for a nice ground connection. Taking a look at the overall measurements, it's going to give us an overall length of about 6 and 1/8 of an inch, an overall width of about 4 and 9/16 of an inch, and then, measuring the depth, it's going to give us a measurement of about 2 and 7/8 of an inch. We're going to go and connect it to our external power source. That way, you can see what it looks like with power running to it, and with our overhead lights turned off. We're going to go and connect the ground wire. Then, we're going to take our tail lights and hook them in. Then, we'll do the same thing for the stop and turn signal. You can see here that it's going to provide a nice, consistent signal for the tail light function, and then when we apply our brakes, it's going to illuminate a little bit brighter for a nice, consistent brake signal, as well as our turn signal. That's going to do it for today's review of part number ST2RB.

This is the square trailer light for the right hand side of our trailer, from Optronics. .

Unfortunately, I just replaced this light, so it did not make the one year mark. The base where the bulb is supposed to lock into failed and did not keep the bulb tight against the contacts. 575016

The product, ST2RB trailer taillight, works as advertised; which is good. I backed into a tree that jumped in my way while turning around on our farm. Since the trailer has to be inspected to register, I have to repair the taillight. After searching the Internet for a replacement, I found etrailer had the correct part and I was fortunate they also have great service. I recommend this part AND this company for great customer service and rapid response to get me the product quickly. Thank you etrailer. 473830

The product, ST2RB, trailer tail light is still going strong. Happy I worked with etrailer to replace my broken tail light. The light is on a 20’ trailer and I do not use it that much anymore but I can take it on the road if I need too!

no instructions. There were no wires coming out of the unit to attach to the existing trailer wires. I took off the cover and saw that it is quite a poor design. it's really no wonder why they are only $6. When I went on your site to look at the "instructions" in the link you have. I got this message: "The instructions you requested are not currently available from the manufacturer. We apologize for any inconvenience" I got only ONE light wired with some head scratching and soldering. Hopefully you'll do better next time. Everything you've sent me to date has been excellent. But... :( 576139

The lamps install using the spring terminals on the rear of the lamp. Simply the stripped wires into the square holes, as mentioned in the video linked above.

Ask the Experts about this Optronics Trailer Lights


  • Troubleshooting Function of Additional Trailer Side Marker/Signal Lights
  • The problem you're having with your new wiring could be related to the ground, especially since it sounds like you may have added more lights than were originally on the trailer. It often happens that weird behavior from trailer lights results from a loose, corroded or insufficient ground connection. First make sure that each individual light's ground is made to clean bare metal. Some lights like # TLL12RK use a wired ground (white wire with ring terminal) while others like # ST52AA...

  • Can a Side Marker Trailer light be Wired to Come On with the Blinker
  • If you want to make a side marker light blink with the turn signal it will have to be tapped into the turn signal/brake light wire for that side. But then it will also come on with the brake lights. And you would not want to also attach it to the running light circuit because it would back feed and lights would come on when they should not. Trailers are made with what is called a 2 wire system. They have combined turn signals and brake lights and the running light circuit is separate. In...

  • Replacement Optronics Side Marker Lens Cover
  • The Replacement Side Marker Lens # A2RB will simply need a screw that fits the 1/4" diameter hole and is longer than 1-1/4", so the choice is yours as there is no recommended hardware. Based on the photo you provided, I do recommend replacing the entire # ST2RB fixture because the plastic housing is pretty clearly damaged. Either way I'm sure your friend will appreciate your gesture.

  • Availability of Replacement Side Marker Lens For Trailer Light PM440
  • You might look at Optronics Replacement Side Marker Lens, part # A2RB. This side marker lens is the same length and width as the Peterson Replacement Lens, part # 55-15R, you have referenced, but is 1-1/2 inches tall. The # A2RB lens will fit on a trailer light like the Optronics Square Trailer Tail Light, part # ST2RB.

  • Replacement Light Bulb For Optronics Square Trailer Tail Light # ST2RB
  • The standard light bulbs in the # ST2RB light is part # A1157B. This bulb features 8.3 watts for the tail light function and 26.9 watts for the turn and brake light function.

  • Trailer Lights Go Out When Headlights Are On
  • It sounds like you could have more than one issue on your trailer but the most prevalent is a weak ground or so it seems. I recommend that you start by checking both the trailer side and vehicle side connector, by check I mean you should remove each of them, sand down the surface and then reattach with new mounting hardware. A visual inspection of the ground terminal is not sufficient to check for function. I would also run a jumper wire on the ground circuit from each tail light up to...

  • Can LED Trailer Taillight Kit TLL160RK Replace Incandescent Square Trailer Lights
  • Theres no reason you couldn't upgrade your square incandescent lights to the rectangle LED trailer light kit part # TLL160RK that you referenced. LED trailer lights are a great option as they basically last forever and only draw a fraction of amperage when compared to incandescent bulbs.
