The LED headlight low beams (if equipped), daytime running lights, front
position lights, side turn signal lights, stop lights, high mounted stoplight

another duly qualified and equipped professional to have the light replaced.

Temporary condensation build-up on the inside of the headlight lens does
not indicate a malfunction. Contact any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional, for more information in

Large drops of water are built up on the inside of the lens.

Water has built up inside the headlight
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. 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.
