What color should the rear headlights of a vehicle be?

The rear headlights of a vehicle should be red or orange-red to ensure visibility and safety. This color is universally recognized as a warning signal for other drivers, indicating the rear presence of a vehicle. Red lights on the backend help convey critical information such as braking or the vehicle's position on the road, especially in low-light and nighttime conditions. This color standard is in place to prevent confusion with the colors of other vehicle lights, such as white headlights at the front or amber signals that indicate turning or lane changes. Ensuring that tail lights and brake lights are red is essential for maintaining clarity on the road and enhancing overall traffic safety.
