WARNING

■ 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

unavoidable 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 headlights 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 installing to prevent heat damage.
