Recently one side(right) of my headlights flickers before turning on or sometimes not at all. Ill have to turn off the headlights and turn them back on for that one side to turn on. I was wondering if any of you guys had any idea what the problem was? The bulbs are fine, since I switched sides and still the same problem with the right side. Any input would be appreciated, thanks.

 

not enough current going to ballast for ignition, check wiring harness and upgrade if necessary
