Lighting system

Summary
The lighting system allows the driver to see when driving at night or in poor visibility conditions, and to signal to other drivers.

Lighting systems improve visibility at night, and make a vehicle visible to other road-users.

A lighting switch operates tail-lights, park lights, and headlights to allow the driver to see ahead. A dip switch allows the driver to change the beams from high to low, or vice-versa, as required.

Stop-lights operate when the brake pedal is depressed.

Turn-signals alert other drivers of a change in direction, and are mounted so they can be seen from the front, rear and sides of the automobile.

An emergency flasher system operates both front and rear turn-signals at the same time.

Other circuits operate courtesy, or convenience lights, reversing lights, and fault indicators.
