High Intensity Discharge (HID) Lighting

WARNING!
The low beam high intensity discharge lighting system operates at a very high voltage.
If you try to service any of the system components, you could be seriously injured. Have your dealer or a qualified technician service them.

After an HID headlamp bulb has been replaced, the beam might be a slightly different shade than it was originally. This is normal.
