XENON HEADLAMP
Xenon type lamps are used for to the low beam headlamps. Xenon bulbs do not use a filament. Instead, they
produce light when a high voltage current is passed between two tungsten electrodes through a mixture of
xenon (an inert gas) and certain other metal halides. In addition to strong lighting power, electronic control of
the power supply gives the headlamps stable quality and tone color.
Followings are some advantages of the xenon type headlamp.

The light produced by the headlamps is white color similar to sunlight that is easy to the eyes.

Light output is nearly double that of halogen headlamps, affording increased area of illumination.

Counter-reflected luminance increases and the contrast enhances on the wet road in the rain. That makes
visibility go up more than the increase of the light volume.

Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.

Trouble Diagnoses EKS00N4Y
WARNING:

Xenon headlamp has a high-tension current generating area. Be extremely careful when removing
and installing. Be certain to disconnect battery negative cable prior to removing or installing.

When xenon headlamp is lit, never touch harness (covered with red or amber insulation), bulb
itself or bulb socket with your bare hands

Never service a xenon headlamp with wet hands.

When checking body side harness with a circuit tester, be certain to disconnect harness connec-
tor from xenon headlamp.

When xenon headlamp is lit, xenon bulb must be installed in headlamp housing. (Never turn on
xenon headlamp, if bulb is out of headlamp housing.)
CAUTION:
Make sure to install bulb securely; if xenon bulb is improperly installed in its socket, high-tension cur-
rent leaks occur. This may lead to a melted bulb and/or bulb socket.
