Are Load Resistors Always Required When Installing LED Lights As Replacements To Incandescent Bulbs

Question:

I ordered a left and right assembly, do I need any load resistors to prevent hyper flashing due to these being LED? Thank you.

For your LED Trailer Tail Light - 7 Function - Submersible - 23 Diodes - Rectangle - Red Lens - Driver # STL57RB there is a good chance you won't need load resistors. Not all LED trailers require load resistors like the Load-Resistor Kit # DI34ZR. It really has to do with the vehicle's wiring as much as the trailer. If you have a hyperflashing issue once you install these lights, I have a couple suggestions. If you have a 7-way trailer connection, then I recommend using the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV - Vehicle End # 20142 which has the load resistor built in.
