The BMW E60 uses xenon headlights. The xenon headlights provide superior visibility over traditional halogen lights, but do require that you have the headlights properly adjusted to avoid blinding oncoming traffic and to make sure that you have optimum visibility of the road ahead of you. Any time you replace the headlight assembly, you should adjust the headlights. Because the lateral movement of the headlights on the E60 is fixed, you can only adjust the vertical alignment of the headlights.
Park your BMW E60 so that it faces a flat surface, like a garage door. Make sure the vehicle is 30 feet away from the door.
Turn the headlights on.
Open the bonnet and locate the adjustment screw on the top of the headlight assembly.
Turn the headlight adjustment screw until the centre of the headlights is at the bottom of the garage door where the door meets the ground.
