What are Tail Lights and Why are They Important?
Tail lights are an essential part of a vehicle’s lighting system. They are located at the back of the car and are used to alert other drivers of your presence on the road. Tail lights act as a warning signal to other drivers that you are braking or turning, especially when driving at night or in low-light conditions.
Without tail lights, driving during the night or in low-light conditions can be extremely dangerous. In fact, not having functional tail lights can even result in police fines or penalties. That is why it’s important to keep your tail lights properly functioning and well-maintained.
