Function of headlights

Imagine driving at night, or during foggy weather or during storms. You wouldn’t be able to see the road in front of you properly or at all. This is a dangerous situation, which is why we need headlights.
In many old models, there are switches that you can press when you need to turn on the lights. You can even control the intensity of the lights through those switches. However, in newer cars, the light has been replaced. The headlights have photoelectric sensors that can detect low light. When it detects low light the headlights will turn on automatically. Remember to use lights when driving through areas that have sparse traffic.
Types of Headlights
