How are headlights required to be mounted on motor vehicles?

Headlights on motor vehicles are required to be mounted one or two on each side at the same level to ensure consistent illumination of the road and improve visibility for both the driver and other road users. This configuration helps create a balanced lighting pattern, reducing the risk of glare for oncoming traffic and enhancing safety during nighttime driving.

Uniform height also supports proper light distribution and alignment, optimizing the effectiveness of the headlights in various driving conditions. While variations in headlight height might serve specific purposes for some vehicles, the standard requirement emphasizes the importance of maintaining a level placement for functional and safety reasons.
