I recently upgraded my HID bulbs from 4100K to the 6000K. I have a after market kit. Since I swapped the bulbs one of the 6000K bulbs isnt working properly, It seems to only come one when it wants to. Now a wrench in the plans is this. While trying to replace my parking bulbs I lost one, SO that same side is also missing a parking bulb, Would that have anything to do with the bulb working sporatically? I would think not because they should be on a different circuit. You guys know how hard it is to change bulbs on out car so I am trying to do and much find and seek before I have to lift the car again. Also one bulb is a slightly different color than the other. Could I just have gotten a bad bulb, or is there another problem. Thanks.
