WARNING:

Comply with the following warnings to prevent any serious accident.
• Disconnect the battery cable (negative terminal) or the power supply fuse before installing, remov-

ing, or touching the xenon headlamp (bulb included). The xenon headlamp contains high-voltage
generated parts.

• Never touch the bulb glass immediately after turning it OFF. It is extremely hot. 

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• Install the xenon bulb securely. (Insufficient bulb socket installation may melt the bulb, the connec-

tor, the housing, etc. by high-voltage leakage or corona discharge.)

• Never perform HID circuit inspection with a tester.
• Never touch the xenon bulb glass with hands. Never put oil and grease on it.
• Dispose of the used xenon bulb after packing it in thick vinyl without breaking it. 
• Never wipe out dirt and contamination with organic solvent (thinner, gasoline, etc.).
