I am having a problem with my 2012 jku headlights. I noticed when driving in the snow the traction control will cause the headlights to dim. Is this normal? The only thing non stock is a set of hella 500ff's that are triggered off a relay connected to the factory fogs which are not on when this happens.

 

This is normal as the traction control system takes a lot of power and it draws from other systems. There was another thread I've started that this was mentioned on.

 

Thanks! I tried a search for flicker and all that turned up was the LED issues. There is a low buzzing noise when the ignition is turned on and I thought something got messed up with a headlight relay.
