FAULT DIAGNOSIS
A Xenon HID system is made up of different components.
Follow the simple checks to replace the correct part.
1) Check the ballast.
You should hear an electrical switching noise around the headlight area,
this is the ballast trying to ignite.
2) If the ballast can be heard then the bulb requires replacing.
3) If no noise is heard then check the relevant fuse (see vehicle handbook).
4) If the fuses are ok, the ballast or wiring are at fault. Consult an auto
electrician.

SAFETY
CHARACTERISTICS
Due to the high start-up voltage approx. 26,000 volts, in a HID system,
safety features have been built in.
1) The Xenon HID system will automatically shut down if a fault occurs.
2) The Xenon HID system will automatically shut down if a cable is removed
during operation.
3) In the event of a failed bulb the system will only try to light the bulb 7
times to protect the ballast electronics.
