on my car i had hids and i noticed the driver side was flickering like a strobe light. today i put my old stock bulbs in and the hi beam is on with the low beam and both are dim i pulled the high beam fuze and lost both lights im getting good power to each i checked all fuzes and circuit breakers i couldnt see any wires touching each other.... any ideas im wanting to go run tonight but i cant with one head light thanks for the help in advance

 

Bad ground connection is a possibility. Check voltage with lights on by back probing the wires at the connector.

 

found it i checked all the voltage ecerything seemed fine then i moved a hose and found a black box with alot of grounds goin to it. i tightened it an was good
