Toyota Corolla (E120): Precaution

- if even a thin film of oil is left on the surface of the halogen lamp, its service life will be shortened because the lamp will be burn at a higher temperature.
- 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.
- 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.
- always use a bulb of the same wattage for replacement.
- firmly reinstall the socket after bulb replacement. The lens may become cloudy or the light cavity may fill with water through the gaps around the socket.
