What color are the reverse lights on most cars?

The reverse lights on most cars are white. This color is standardized and serves a specific purpose: it provides illumination when a vehicle is reversing, ensuring that the driver can see clearly behind the car and making the vehicle more visible to others. The use of white lights in the reverse function helps in distinguishing these lights from other vehicle lighting, such as brake lights, which are red, and turn signals, which can be amber. This differentiation is crucial for safety, as it signals to other road users that the car is backing up. The clarity of the white light makes it easier for others to recognize the vehicle's intentions, reducing the likelihood of accidents.
