How many lights must be present in front of a vehicle and what are their colors?

The requirement for vehicles to have specific lights in front is crucial for safety and visibility. Vehicles must be equipped with two lights located at the front, and these lights must be either yellow or white. This design choice allows for adequate illumination of the road ahead, making it easier for drivers to see and for others to see them, especially in low-light conditions.

Using yellow or white lights is standard practice in many regions, as these colors are effective for visibility without causing confusion for other road users. In contrast, red, green, or blue lights have different uses and regulations associated with them, primarily indicating warning signals or emergency vehicles. For instance, red lights typically indicate stopping or caution and are not suitable for standard moving vehicles, while blue lights are usually restricted to emergency services. Therefore, the correct answer aligns with established traffic safety regulations regarding vehicle lighting.
