A tail light or a tail lamp is the part of the lighting system of a vehicle which is attached in front and at the rear part of the vehicle. They usually come in pairs (left and right). It has different types for different functions.
The signal lights, or turn lights, are parts of the tail lamp assembly. Usually yellow in color because of regulatory standards, these indicate whether the vehicle is going to turn right or left. They are also used during times of emergency. The reverse lights are also parts of the tail lamp assembly to indicate if the vehicle is backing up. The reverse lights automatically turn on when the driver puts the vehicle in reverse shift. These lights often have the highest illumination in the tail lamp assembly but not as bright as the head lights.
The park light in the tail lamp assembly signals the drivers behind that there's a presence of another vehicle whenever it is dark, foggy or rainy weather. It is also used as a brake light. The park light usually has the highest part in the assembly which turns on as the driver steps on the brakes.
