PRECAUTION
1. PRECAUTION OF HEADLIGHT BULB REPLACEMENT
(a) If even a thin film of oil is left on the surface of the halogen lamp, its service life will be shortened be-
cause the lamp will be burn at a higher temperature.
(b) Handle any halogen lamp with great care. Dropping, hitting or damaging the bulb, in any way, may
result in it exploding and scattering because the internal pressure is high.
(c) Always prepare a new bulb for immediate replacement. While replacing the bulb, the lens may attract
dust and moisture if removed from the vehicle for too long.
(d) Always use a bulb of the same wattage for replacement.
(e) Firmly reinstall the socket after bulb replacement. The lens may e cloudy or the light cavity may
fill with water through the gaps around the socket.
