Just got back form the dealer with having some fluids changed and replaced a burnt out DRL bulb. Got back home and towards dawn the HID's automatically kicked in. Everything looked ok but I did not realize after I got home that the passenger side HID was significantly dimmer than the drivers side. Up unitil the day before it was fine as we were out driving at night. Now the road is hardly lit up since only one HID is at full capacity. What gives? Could the dealer have accidentially done something to loosen a wire.. I did a quick google search and it suggests a faulty ballast? no idea what that means. Back to the dealer tomorrow

Its like one headlight is on a dimmer and its hardly high intensity. My car is just under 2 years old...
