Expert Answers about Sealed, 6-1/2" Oval LED Trailer Stop, Turn and Tail Light, Flange Mount, 10 Super Diode - STL78RB                                           Do you have a question about this 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.
