Morimoto LED PWM Modules for LED Bulbs : 2Stroke 3.0 / 4.0 (Pair)

FLICKER-FREE: Is the way to be! But unfortunately if you're trying to run a set of LED headlight bulbs on a circuit that runs off pulsed voltage, then you're out of luck. Out of luck unless you've got a set of the 2Stroke Anti-Flicker harnesses that is!DESIGNED: With some massive 10K mF Capacitors inside to help absorb the pulsing current coming from the factory wiring, then release it in a smooth fashion out into the LED bulb drivers, they're quite simple and effective.IN AND OUT: No need for complicated wiring to solve this common issue. The 2Stroke Anti-Flickers are easy to setup. With matchings inputs / outputs, you can just "plug n play" in between the factory wiring and the Drivers on your bulbs.DAYTIME RUNNING LIGHTS: Often run off both pulsed voltage, and low voltage. It's important to understand which one your car uses - because if you're having issues with a low voltage setup, these will not solve that problem (since they don't increase the voltage coming from the car...
