■

LED high mounted stoplight

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. 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. 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.

■

To prevent damage or fire

Make sure bulbs are fully seated and locked.
