Helpful Expert Reply:

The flicker you are referring to with LED bulbs is known as hyper flashing. This occurs because the LED bulbs require so much less power than incandescent bulbs. So when your lights are on, the power to the bulbs is reduced due to the draw on the headlights and running lights, but when they are turned off the power is too great for proper function without adding load resistors. I recommend adding the Putco LED Light Bulb Load-Resistors - Aluminum - Qty 2 # DI34ZR to your wiring for each LED bulb. This will create a draw similar to the incandescent bulbs and keep the LED bulbs from flickering.
