CAUTION
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. 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. 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.
While the headlights are turned on, and
for a short time after they have been
turned off, metal components at the rear
of the headlight assembly will be
extremely hot. To prevent burns, do not
touch these metal components until you
are certain they have cooled down.

CAUTION
Discharge headlights
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional before replacing the discharge headlights
(including light bulbs).
Do not touch the discharge headlight’s high voltage socket when the head-
lights are turned on.
An extremely high voltage of 30000 V will be discharged and could result
in death or serious injury by electric shock.
Do not attempt to take apart or repair the headlight bulbs, connectors,
power supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.
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.
NOTICE
When replacing the outer foot lights
If the front window is stopping you from conducting the replace operation
properly, open the window on the side you are working on to allow you
enough space to work. Continuing the operation without giving yourself
enough space to work could lead you to scratch the vehicle.
