The lights on a vehicle have different functions and are an important part of road safety. The lights of your vehicle improve visibility at night. They also ensure that other road users can better see the presence, position, size and direction of your vehicle.
The low beam lights illuminate the road without dazzling other road users, they illuminate the road to about 30 meters. The red tail lights also illuminate when the dipped beam is switched on. The low beam is the standard lighting that you have to use when it gets dark.
The high beam is used to illuminate the road so that you can see further, it provides a clear view to about 100 meters. Because the high beam emits a very bright light, it can blind other road users. You may not use the driving beam if you drive behind another road user or when approaching an oncoming vehicle.
The fog light may be used in bad weather conditions such as heavy rain, fog, or snow. The fog light can dazzle other road users, so use it only in bad weather. Not all cars are equipped with fog lights, so they are not required to use.
The direction indicators are flashing lights on the left and right front and rear of the vehicle. Sometimes also on the sides or on the side mirrors of a vehicle. They are used to indicate the direction to other road users when turning or changing lanes.
With most vehicles you can blink the four direction indicators simultaneously. These are the warning lights, they may only be used to warn other road users of a hazard.
