CAUTION
■Replacing light bulbs
● Turn off the headlights. Do not attempt to replace the bulb immediately
after turning off the headlights. 
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. Hold the
bulb by the plastic or metal portion. 
If the bulb is scratched or dropped it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failing 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.
● Do not attempt to repair or disassemble light bulbs, connectors, electric
circuits or component parts. 
Doing so may result in death or serious injury due to electric shock.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.
