Toyota Corolla (E120): Precaution
1. Precaution of headlight bulb replacement
- 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.

Basic inspection
Resistance measuring condition of electronic parts
unless stated, all resistance is measured at an ambient
temperature of 20 c (68 °F). As the resistance
may be outside the specifications if measured at high temperatures
immediately after
the vehicle has been running, measu ...
