The incandescent light bulb was for a long time the only light source used in automotive lighting. Incandescent bulbs are still commonly used in turn signals to stop hyper-flashing of the turn signal flashers. Many types of bulbs have been used. Standardized type numbers are used by manufacturers to identify bulbs with the same specifications.

The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
The automobile self starter was an early engine system to use this. Lighting, which had previously been provided by kerosene lamps or gas lamps, was one of the first common electrical accessories. Early systems used 6 volts, but 12 volts became the standard because it provided greater power with less current.
