Tail lights, also known as taillights or tail lamps, are lights that are mounted at the rear of a vehicle. They serve a number of functions, including signaling to other drivers when you are stopping or slowing down, increasing the visibility of your vehicle to other drivers, and helping to make your vehicle more visible in low-light conditions. Tail lights typically consist of a series of bulbs or LEDs that are arranged in a specific pattern and are encased in a housing that is mounted to the rear of the vehicle. The housing is usually made of plastic and is designed to protect the bulbs and wiring from the elements.
