Notes on bulb replacement

Only use 12-volt bulbs of the same type
and with the specified watt rating.


Switch the lights off before changing a

handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not

Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before chang-
ing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas.
A bulb can explode if you:

touch or move it when hot

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.
