son broke the passenger side light so i just replaced both of my head lights assemblies with new bulbs and now the passenger side is at 1/8th or less intensity wit both bulbs illuminated while the drivers side is at full intensity and will cycle from high to low. Passenger side will not cycle and when i remove either one of the bulbs it causes the other bulb to go out . the driver side isn't affected at all. any ideas?

 

bad ground?
