headlight problem
okay on the driver side the headlights is out. so I bought new bulbs and installed it and turned it on and it went on and went out. I keep twisting the headlight switch on and off. it would keep going out till I turned it enough where it stayed on. Does anyone know what the problem is?

Year? Model/Engine? HID/Xenon or Halogen?
If stock xenons - test your ballasts on the side giving you trouble. This will require removing it from bad side A to good side B and reconnecting it. If side B still lights up with no problems, ballast A is good. It could also be the bulb if you bought generic eBay bulbs, or touched the bulb itself with your bare hands a lot while installing (oily hands = no-no for xenons).
