General Precautions For Service Operations

Never work with wet hands.
Turn the lighting switch OFF before disconnecting and connecting the connector.
When checking the headlamp on/off operation, check it on vehicle and with the power connected to the vehicle-side connector.
Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the performance of the lens and reflector (dirt, clouding). Always prepare a new bulb and have it on hand when replacing the bulb.
Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.
