hey one of my headlights is brighter than the other one. i installed the xenon headlights and one kept going out so i fiddled with it a bit until it started working all the time. about a day later i pulled into a parking space and noticed that the one that i had fiddled with was brighter than the other one. i think that is the way that both of them are supposed to be so i messed with the less bright one but it hasnt changed. any idea as to how this works?
