Everything arrived packed in box very nice. Your service was quick. I really appreciated that you took the time to keep me updated on the shipment. It is really nice that you have the section with wiring diagrams. It might seem like a small thing but it sped things up for me as I did rely on it a few times. Your prices and products were great. I would say you have a lot of pride in your company. The next time I need trailer parts I will definetly order from you. Thanks again, Steve M. 43771

Ask the Experts about this Optronics Trailer Lights


  • Best Method for Attaching Tail Lights to Aftermarket Flat Bed on 2008 Nissan Titan
  • I do not have a source for a plug that would mate with the factory harness for your OEM tail lights. Your best bet will be to use a circuit tester like part # 3808 and test the wires in the rear harness to determine their function. The black wire on the replacement tail light will attach to the running light circuit, and the red wire attaches to the turn signal/brake light circuit. Using quick splices like part # 804C would be the simplest method of making your connections. If you go this route

  • LED Tail Light # STL78RB Recommendation for a Coleman Popup Camper
  • It sounds like the LEDs that you previously had installed on your trailer were single function LED lights, and that is why if they saw any power they were lit regardless if different blinker, tail light functions were being applied at the same time. These Optronics Trailer Lights, part # STL78RB, that you referenced are designed for all of the different stop, turn, and tail light functions and should work very well for you.

  • Recommendation for Flashing or Strobe Tail Lights for Use on a Tractor
  • We do have some LED lights that strobe but none in red that are shaped like an oval. For a similar set of lights that do flash with power applied to them, take a look at # CPL65A-STR. These are amber lights. For red flashing lights, we have # CPL4R-STR. These are 4 inch diameter round lights. Any of the strobing lights we do carry will only act flash and will not have any other functions.

  • Is the Optronics LED Trailer Stop, Turn and Tail Light Assembly # ATL78RB Sold Individually
  • The Optronics LED Stop, Turn and Taillight you referenced # STL78RB is sold individually. If you need two of them, be sure to state that you need a quantity of 2.

  • Are Load Resistors Required When Installing LED Lights on a Trailer
  • You will not need to add any diodes or other modules to prevent hyperflashing or any other bizarre taillight behavior when you install this Optronics Tail Light # STL78RB on your trailer. If you were installing LED tail lights on a vehicle and replacing the lights on the turn signal circuit then you would need a load resistor so that the blinkers would function correctly.

  • Can Trailer Hitch Mount Cargo Carrier # 63155 be Used with a Different Light Kit
  • I went out to the warehouse and measured the opening for lights in the cargo carrier, # 63155. The opening itself is 6-3/4 inches long by 2-1/2 inches tall. The bracket part of the carrier that the light sits in is 7-7/8 inches long by 3-1/2 inches tall. You would be able to drill some holes and mount light # STL78RB to the bracket part of the carrier. It mounts on holes that are 7 inches apart lengthwise and 2-3/4 inches apart top to bottom. You would really only need the 2 side mounting poi

  • Optronics Oval LED Light Recommendation to Replace an Older Style Optronics Light
  • I do have a solution that should work for you, but we do not carry any Optronics lights with the style connector you have. You could get a Optronics Trailer Light # STL78RB that you referenced, and to install it you would just want to cut of the connector that is on your trailer and then wire the the three wires to the wires of the # STL78RB. The white wire of the # STL78RB will run to the ground wire of your trailer wiring, the red will run to the turn signal/brake wire and the black will ru

  • Will Optronics Turn and Tail Light # STL78RB Need Additional Power Source on 2013 Toyota Camry
  • To use the Optronics 6-1/2-Inch Turn and Tail Light # STL78RB with your 2013 Toyota Camry, you will not need an additional power source. Each of these lights draw draw a fraction of the power of incandescent bulbs and are DoT-compliant.
