[98blkm3]

ok i bought the depo glass headlights the thing is the passenger side works perfect, angel eyes high beam and the hid low beam. when i put the driverside in the high beam and angel works perfect just the low beam hid wont work. the wires use the ballast to function so tried two different ballast and same problem so i hooked a stock bulb and connector to the stock wiring harness from the car and still did not work the stock bulb. my car is a 98 m3 please if someone knows whats going on or can point in the right direction it would be much appreciated thankyou for your time...

Umm, are you using the light bulb grease for the connectors, etc? And are you making sure that there are good contacts for the low beam? I had this problem on a Camaro a while back, and it literally turned out to be a bad connection to the bulb. Some bulb grease and creative bending of the connectors fixed the problem.

Check the fuses.

My Hid only fired up on both sides after I plugged the ballast into the harness to the car backwards. Go figure.
