Notes on bulb replacement
Only use 12 volt bulbs of the same type 
and with the specified watt rating. 
Switch lights off before changing a bulb

Your hands should be dry and free of oil 
and grease.
If the newly installed bulb does not

Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing 
a bulb.
Halogen lamps contain pressurized gas. A 
bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is 
dangerous to replace the bulb or repair the 
lamp and its components. We recommend 
that you have such work done by a qualified 
technician.
iHave the headlamp adjustment 
checked regularly.
