Before performing any light bulb replacement procedure, be sure to turn the power

Replacing light bulbs

●

Turn off the lights. Do not attempt to replace the bulb immediately after turning off the

lights. 

The bulbs become very hot and may cause burns.

●

Do not touch the glass portion of the light bulb with bare hands. When it is unavoid-

able to hold the glass portion, use and hold with a clean dry cloth to avoid getting

moisture and oils on the bulb.

Also, if the bulb is scratched or dropped, it may blow out or crack.

●

Fully install light bulbs and any parts used to secure them. Failure to do so may result

in heat damage, fire, or water entering the headlight unit. This may damage the head-

lights or cause condensation to build up on the lens.

Doing so may result in death or serious injury due to electric shock.

■

To prevent damage or fire
