Opel Corsa B 1993–2000 Service and Repair Manual: Bulbs - renewal

General

1. Whenever a bulb is renewed, note the following points.

1. Disconnect the battery negative lead before starting work.
2. Remember that if the light has just been in use the bulb may be extremely hot.
3. Always check the bulb contacts and holder, ensuring that there is clean metalto- metal contact between the bulb and its live(s) and earth. Clean off any corrosion or dirt before fitting a new bulb.
4. Wherever bayonet-type bulbs are fitted (see Specifications) ensure that the live contact(s) bear firmly against the bulb contact.
5. Always ensure that the new bulb is of the correct rating and that it is completely clean before fitting it; this applies particularly to headlight/foglight bulbs.
