Lexus NX: Precaution

PRECAUTION

PRECAUTION FOR HEADLIGHT BULB REPLACEMENT

(a) If even a thin film of oil is left on the surface of a headlight bulb, its service life will be shortened because the light will burn at a higher temperature. When replacing a bulb, be sure to hold the flanged part of the light so that your hand does not contact the glass part of the light.

(b) As the internal pressure of headlight bulbs is high, dropping, hitting or damaging a bulb may result in it exploding and shattering.

(c) Always prepare a new bulb for immediate replacement. While replacing a bulb, the lens may attract dust and moisture if removed from the vehicle for a long time.

(d) Always replace a bulb with another bulb of the same wattage.

(e) If only replacing the bulb on one side, differences in brightness and lighting color between the right and left sides may occur.

(f) Securely install the socket after bulb replacement. The lens may become cloudy or the light cavity may fill with water through gaps around the socket if the socket is not installed securely.
