■Replacing light bulbs
●Turn off the lights. Do not attempt to replace the bulb immediately after turning off the

moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.

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.
■To prevent damage or fire
●Make sure bulbs are fully seated and locked.
●Check the wattage of the bulb before installin g to prevent heat damage.
