Section 390 (Lighting System): Precaution

WARNING: This page is about a different car, the 2004 Lexus GX 470. However, it is still accessible from the selected car via links, so may be relevant.

PRECAUTION OF HEADLIGHT BULB REPLACEMENT
1. If the adhered oil is left unremovable from the halogen lamp surface, the lamp service life is shortened as it becomes hot when it is turned on.
2. Since the internal pressure of a halogen lamp is high, dropping, hitting or damaging the bulb may cause the glass to scatter. Therefore, handle it with great care.
3. When replacing a bulb, do not remove it until a new bulb is prepared because if it is left being removed for a long period of time, the lens may be covered with dirt or moisture.
4. Be sure to replace with a bulb of the same watt.
5. Firmly reinstall the socket after replacing a bulb. Otherwise, cloudy lens or water leakage will be caused.
