Question:

Does your Optronics light STL42RB require a resistor 3-prong pigtail on the turn lights so that they blink correctly?

Helpful Expert Reply:

The Optronics Round LED Trailer Stop, Turn and Tail Light # STL42RB does use a 3-prong plug for electrical connection. We offer right-angle 10-inch pigtail plug # A47PB and straight pigtail plug # A45PB.

Neither of these includes a load resistor, which can be required on some wiring systems to mimic the higher electrical resistance of standard incandescent lights. Some turn signals will hyper-flash when used with LED lights because the wiring does not "see" the load from the super-high-efficiency LED lights. For a 3-prong plug WITH load resistors you can use part # ALEDRST2B or part # ALEDRST1B.

We do also offer load resistors alone, like # DI34ZR.

The need for load resistors will depend on the vehicle and wiring harness kit. Using them will not harm anything.
