A standard vehicle tail light assembly typically incorporates three distinct illumination functions. These are the brake light, the turn signal indicator, and the tail light itself (also known as a running light). Each performs a specific role in vehicular communication, enhancing road safety.
The proper functioning of these lights is critical for accident prevention. Brake lights alert drivers behind that deceleration is occurring. Turn signals communicate intended direction changes. Tail lights provide visibility during low-light conditions, indicating the presence and position of the vehicle. Their consistent operation has been a fundamental aspect of automotive safety design since the early days of motoring.
