The **high beam headlights** or **main beam headlights** are designed for use on **roads outside towns or cities**. These lights are useful when driving at night on roads with little natural light and at speeds over 40 km/h, or in tunnels outside a municipality that are not well lit.

However, it is **prohibited** to use high beam headlights within **towns and cities**. This is because these lights can dazzle other drivers and pedestrians, creating dangerous situations. Therefore, on through roads, which are parts of the road that pass through urban areas, these lights should not be used under any circumstances.


Instead of high beam headlights, **low beam headlights** or **dipped beam headlights** should be used on through roads. These lights are mandatory at night on all types of roads, both inside and outside towns and cities, and help to avoid dazzling other road users.
