A car, truck or a Sport Utility Vehicle all use lights for a multitude of reason. The most popular ones are the headlights, this is the most recognizable, and then there are the taillights, also very popular with modifications. These are used for visibility and for safety. There also a number of warning and signal lights installed. This is to signify the intentions of the driver in the course of his drive. These are installed in the rear and the back at the corners. With every turn they make they can let other motorists know their intentions to do turns. These lights are important chiefly for the safety and welfare of the motoring public.
