What color should the headlamps be on a vehicle?

The headlamps on a vehicle should be white or amber. This standard is established to ensure visibility and safety on the roads. White lights provide the best illumination for both the driver and other road users, helping to increase visibility during nighttime driving or in low-light conditions. Amber lights are often used for turn signals or markers because they can be easily seen and understood by other drivers, reducing the risk of confusion.

In contrast, other color options like red or blue are specifically designated for emergency vehicles. Green or yellow lights and unconventional colors like pink or purple may not be recognized as standard for headlamps and could potentially confuse other motorists, leading to unsafe driving conditions. Thus, adhering to the regulation of using white or amber headlamps aligns with traffic laws and promotes safety on the road.
