CAUTION
Replacing light bulbs
■
Turn off the headlights. Do not attempt to replace the bulb immediately after turn-
●
ing 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.
High-intensity discharge (HID) headlights
■
Contact your Lexus dealer before replacing high-intensity discharge headlights
●
(including light bulbs).
Do not touch the high-intensity discharge headlight' s high voltage socket when
●
the headlights are turned on.
An extremely high voltage of 20000 V will be discharged and could result in
death or serious injury by electric shock.
Do not attempt to repair or disassemble light bulbs, connectors, electric circuits
●
or component parts.
Doing so may result in serious injury due to electric shock.
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.
