rary condensation build-up on the inside of the headlight lens does not indicate a
malfunction.

go out temporarily. The discharge bulbs will come on when normal power is
restored.

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 en tering the headlight unit. This may damage
the headlights or cause condensation to build up on the lens.
