What color must the parking lamps be for all passenger cars and multipurpose passenger vehicles?

The parking lamps for all passenger cars and multipurpose passenger vehicles must be amber or white. This standard ensures visibility and safety on the road, as these colors are easily recognizable to other drivers and pedestrians during low-light conditions.

Amber is particularly noticeable and is often used in various types of vehicle lighting to indicate the presence of a vehicle while parked, helping to prevent accidents by alerting other drivers that there is a vehicle in proximity. White lamps are also commonly used for visibility, especially in parking situations, enhancing overall safety.

The other color combinations presented do not meet the standards for parking lamps and could create confusion or be less effective in notifying others about a parked vehicle. Using red, for example, may be associated with stop signals or warnings, while colors like green and blue do not convey the necessary information about the vehicle's position on the road.
