Maintenance
Always handle them carefully, and
avoid scratches and abrasions. If
the bulbs are lit, avoid contact with
liquids.
Never touch the glass with bare
hands. Residual oil may cause the
bulb to overheat and burst when lit.
A bulb should be operated only
when installed in a headlamp.
If a bulb becomes damaged or
cracked, replace it immediately
and carefully dispose of it.

Maintenance
Information
If your vehicle is equipped with High
Intensity Discharge (HID) headlamps,
these headlamps contain mercury. So
if you need to have your vehicle dis-
posed, you should remove the HID
Headlamps before disposal. The
removed HID headlamps should be
recycled, re-used or disposed as haz-
ardous waste.
Information
HID lamps have superior perform-
ance vs. halogen bulbs.
HID lamps are estimated by the man-
ufacturer to last twice as long or
longer than halogen bulbs depending
on their frequency of use. They will
probably require replacement at some
point in the life of the vehicle. Cycling
the headlamps on and off more than
typical use will shorten HID lamps
life. HID lamps do not fail in the same
manner as halogen incandescent
lamps. If a headlamp goes out after a
period of operation but will immedi-
ately relight when the headlamp
switch is cycled it is likely the HID
lamp needs to be replaced. HID light-
ing components are more complex
than conventional halogen bulbs thus
have higher replacement cost.
Information
The headlamp aiming should be
adjusted after an accident or after the
headlamp assembly is reinstalled at an
authorized HYUNDAI dealer.
