Tail lamps are typically mounted at a caudal section of a vehicle to provide a noticeable warning to a following driver at the start of a vehicle operation and so the following driver would be able to take a proper evasive action. Generally speaking, a vehicle lamp is mainly grouped into a headlamp installed at a front of a vehicle and a tail lamp mounted at a back of a vehicle. The tail lamp performs functional roles, for example a brake operation display, a direction display, and also an alarm display, it also has an aesthetic role for forming an image of a rear of a vehicle. It is important for a driver to keep a safe distance from a vehicle ahead while driving to circumvent the possibility of a car accident. Specifically, in vehicles with a high speed drive, the distance between vehicles rapidly and continuously changes as a result of variation of the relative velocity between them, and for that reason the driver of a vehicle following from behind must pay close attention to the front vehicle for indications that the front vehicle will decelerate or stop (many times quickly). Vehicle taillights typically perform a mixture of functions: a taillight function, delivering continuous illumination; a stop function, providing illumination when the vehicle's brake is engaged; and also a turn light function, providing intermittent illumination as the vehicle's turn signal is engaged. A tail lamp may include a brake light, a tail light, a turn signal light, and a backup light. The brake light is switched on whenever the brake is engaged to warn the drivers of following vehicles. Such lights were typically provided proximate the rear bumper or trunk, but as time goes by, regulations were passed to mandate additional brake lights to also be placed higher, proximate the rear window with the intention to be more in the line-of-sight of the approaching vehicle. The taillight also secures the driver's field of vision, particularly when driving in the dark or during low lighting conditions. Stop lamps that illuminate when a brake pedal is pushed down are provided in the rear of a vehicle. The light emitted by the stop lamps notifies a driver following the vehicle from behind to maintain a safe distance by indicating that the brake pedal is being pushed down by the driver. The brake light and the tail light may be incorporated into a single lamp or can be implemented as separate lamps based on the type of the vehicle. In general, the brake light is often designed to be brighter than the tail light. Stop lamps are designed to deliver a steady warning light to the rear of a vehicle, to indicate the intention of the driver to slow down or to stop. The center high mounted stop lamp, (CHMSL) is an automotive stop lamp so mounted that allows the driver to alert the following vehicle as well as through intervening vehicles. It is employed in addition to other stop lamps in the brake system.
