What are acceptable colors for vehicle headlights?

The acceptable colors for vehicle headlights are white or yellow. These colors are standard in most jurisdictions as they provide the best visibility and are most effective for illuminating the road ahead. White light is the most common choice, as it closely resembles daylight and allows drivers to see clearly at night or in low-visibility conditions. Yellow lights are also used in certain situations as they are less likely to cause glare for oncoming drivers.

Other colors, like red or green, are typically reserved for specific uses, such as warning lights on emergency vehicles or certain signals, and are not suitable for headlights. Amber or blue lights are usually associated with certain types of vehicles, such as construction or emergency services, and are not permitted as standard headlights on most vehicles. The use of any color beyond white or yellow for headlights could create confusion on the road and pose a safety risk.
