The bulbs become very hot and may cause burns.

moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.

in heat damage, fire, or water entering the headlight unit. This may damage the head-
lights or cause condensation to build up on the lens.
●Do not attempt to repair or disassemble light bulbs, connectors, electric circuits or
component parts.
Doing so may result in death or se rious injury due to electric shock.
■To prevent damage or fire
●Make sure bulbs are fully seated and locked.
