Phototherapy

Light therapy is the way you treat light on the roads, partly your own headlights but also oncoming traffic and other light sources.

When driving in the dark, it is important to avoid looking directly at bright lights as it dazzles you and limits your driving ability. Instead, you should look far ahead along the higher roadside if you have an appointment.

When driving with high beams, it is important to make sure that you do not dazzle oncoming traffic. If you meet someone in a turn, you can often have the high beams on a little longer as your light pattern mostly goes directly in front of your bonnet.
