The low beam is the headlight you turn on at dusk and dawn to illuminate the road ahead. The light reaches about 165 to 197 feet. It gives you better visibility without dazzling oncoming traffic.
When you turn on the low beam, the front headlights and rear taillights illuminate. If your vehicle is heavily loaded, it may be a little lower. The angle of the light cone changes and can dazzle oncoming traffic. You need to readjust the headlights.
When do I have to switch on the low beam?
You must switch on the low beam in the following situations:
- at dusk and at night;
- in poor visibility conditions due to rain, snow, or fog;
- in tunnels, in parking garages, and when towing.
You can also switch on the low beam during the day as an alternative to a daytime running light. However, it does not replace this because it illuminates the road and not oncoming traffic. It also consumes more energy.
