The best way to stop hyper flashing which is the flickering you are referring to on your LED light bar is to add load resistors like the Diamond LED Light Bulb Load-Resistors - Qty 2 # DI34ZR. You do need make sure the load resistor is grounded properly to get the correct function. The LED lights don't draw as much power as incandescent lights so there are sometimes issues with this hyper flashing until a resistor is added to increase the amperage draw to resemble incandescent lights.

If you have turned off the light bar and removed fuses and it was still flashing, then you have some sort of a storage capacitor in your lights. There should be no power getting to the light bar, so you will need to contact the manufacturer of your light bar if the load resistor doesn't solve that issue. The load resistor will increase the draw needed for the light to function, so I recommend adding it after the fuses and switch.

That flicker is most likely your vehicle checking the trailer wiring circuit for a trailer connection and since LED light bars draw such a low amount of amperage you end up seeing a flicker. So what you could do to simulate a higher amperage draw on…

Answer 3

You are correct, the turn signal circuits are the only ones affected by the hyperflashing, so you won't need a load resistor on the running light, brake or reverse circuits. I've linked to an installation video for a different load resistor…

You will want to wire in a load resistor to any LED bulb that flashes quickly. Basically, the vehicle thinks a bulb is burnt out so you need to add a small load (resistor) to allow the bulb to stop flashing. The resistor gets wired into the…
