Lesson
Components of the Lighting System
The lighting system of a motor vehicle consists of lighting and signaling
devices mounted or integrated to the front, rear, sides, and in some cases the
top of a motor vehicle. This lights the roadway for the driver and increases the
visibility of the vehicle, allowing other drivers and pedestrians to see a vehicle's
presence, position, size, direction of travel, and the driver's intentions regarding
direction and speed of travel. Emergency vehicles usually carry distinctive
lighting equipment to warn drivers and indicate priority of movement in traffic.
The vehicles use electric lighting to provide the illumination or light needed to
safely operate the vehicle especially night time, the various lights provide vision
and information to the driver to other drivers and pedestrians. The automotive
lighting system consists of the components. A wire, switches, relays that operate
the interior and exterior lights on car.
