Went out for a drive last night and discovered something. I never really drove it at night before so I never noticed this. I left my last stop and turned the lights on and by the time I got home (20 minutes or so) the passenger side low beam was out. Figured maybe I blew the bulb. This morning I come down and turn them on and it works for a few minutes and then goes out. Now it was upgraded to an H4 low beam and someone obviously wired it so all 4 lights come on when you flip to high beam. I'm thinking this may be part of the issue or a failing relay. I am however getting .5VDC on the high beam side just on passenger side when it's on low beam which I an tracing now. Are all 4 lights supposed to come on when in high beam or just the inside 2?
