What is the stipulation for the use of driving lamps?

Driving lamps, also known as auxiliary driving lights, are specifically designed to enhance visibility primarily during nighttime driving conditions. The regulation permitting their use only with high beam headlights ensures that they work together effectively to provide better illumination of the road ahead without causing glare for oncoming traffic.

When high beams are in use, driving lamps can help cast a broader and brighter light, aiding drivers in spotting obstacles, road signs, or other vehicles from a distance. This combination is essential for ensuring safety, as it maximizes visibility while minimizing the risk of blinding other drivers.

Using driving lamps with low beam headlights is not permitted because low beams are intended for use in situations where the brightness needs to be reduced to avoid dazzling oncoming drivers. Therefore, integrating driving lamps with high beams only aligns with safety regulations that promote responsible and effective vehicle lighting practices.
