In addition to headlights, taillights, turn signals and license-plate lights, there are numerous lights in the car interior that must be replaced periodically. Also, fuses occasionally need replacing.
- Headlights
Sealed-beam headlights are the most common; many state laws require this type of headlight. When a nonsealed headlight goes out, only the bulb needs to be replaced. Sealed-beam headlights must be replaced as an entire unit. In addition to conventional headlights, quartz-halogen headlights offer nearly double the candlepower but are also more expensive.
- Exterior Lights/Bulbs
Although d-i-yers may have to remove the light lens, a whole light assembly or reach the light from under the fender or bumper, exterior light bulbs are still relatively easy to replace. Usually, the only tool needed to reach a defective exterior bulb is a screwdriver. To remove the bulb, push it into its socket, turn it and lift it out; then replace it with a new bulb.
- Interior Bulbs/Fuses
There are several bulbs in an auto’s interior. Replacement can be as simple as putting in a new bulb to as difficult as disassembling the dash and other components. Fuses are usually easy to reach and replace. Fuses prevent the electrical system from overheating. Fuses, which are either glass-tube types or ceramic, blow as the result of shorts in the system. Glass-tube types are in most American cars; ceramic fuses are used in some imports. When replacing a fuse, it is best to suggest using a special fuse puller. Point out that pullers are much easier and safer than trying to pry out a fuse with a screwdriver.
