LIGHTING
DESCRIPTION AND OPERATION 86-2-17
The bi-xenon dip/main beam headlamps use ellipsoidal technology for the lens and reflector providing improved night
time visibility compared with conventional halogen headlamps. The bi-xenon headlamps provide the following benefits
when compared to halogen headlamps:
l
Longer bulb life – Approximately 3 to 5 times longer than a halogen bulb
l
Increased light output – Xenon headlamps output 2.5 to 3 times more lumens than halogen headlamps (lumens
is a measure of light energy emitted per second on a given area over a given distance)
l
Blue/white light which simulates natural daylight – Xenon bulbs produce a blue/white light compared to the yellow
light produced by a halogen bulb.
l
Improved night time driving visibility – Xenon lamps produce a wider and brighter beam in front of the vehicle
than conventional halogen bulbs.
l
Lower operating temperatures
l
Lower power consumption.
