not sure about the relay but ive had no problems with the 9004 people flash me all the time when i drive with the low beams on (only to be blinded and pissed off by me flasing the high ones back at them..) mabye the problem isnt so much the bulbs as it is the light housing. pull it off and give it a good scrubb or just buy new ones.SoCalB14 said:Well I have 9007's in the car because 9004 are as bright as a lighter. Since 9007's are a much better setup, I installed those, but now have the stupid headlight problem -- I'm thinking it is drawing too much current through the circuit. Quick ? -- Has anybody tried to use a relay with the low beam? (The high should be fine, it's still 65w) The relay should reduce the current to next to nothing on that circuit and even boost the voltage slightly to the 9007 bulbs.
I really don't want to go back to the 9004's.
