How many high-beam lights must a car have (except for vehicles such as motorcycles)?
Lighting
Explanation
Cars must have an **even number of high-beam headlights**. These lights, also known as main beam headlights, are essential for illuminating long distances in front of the vehicle, especially on roads outside towns or cities. They are mandatory for all cars and optional for mopeds.
- High-beam headlights are **white in color** and have high power, which can dazzle other drivers if not used properly.
- They should be turned on in low natural light situations, such as at night or in poorly lit tunnels outside municipalities.
- It is important that the lighting system is in good condition. If any light fails, speed should be reduced and the working lights should be used until reaching a safe place to repair the system.

Therefore, having an even number of lights ensures adequate and uniform illumination, improving visibility and safety on the road.
