Learn how to use mile lights

It is very common to see drivers who run using the equipment in the wrong way

Just walk around the streets a bit to see drivers running with all the lights on, using only the headlights and fog lights, among other combinations. Maybe they think their cars (or even their own) look better. Whatever the reason, using headlights and lights incorrectly can cause an accident or annoy other people. Learn how to choose each one according to the situation.

Position light / flashlight

This type of lighting does not replace the low beam. It is positioned at the front and serves to alert pedestrians and drivers of the presence of your vehicle when it is parked or maneuvering. Position lights can also be used during the day, although they have little effectiveness in bright environments

Low beam

It must be activated at night and situations such as fog, roads, tunnels and dark places. The equipment is sufficient to illuminate a stretch of approximately 40 meters ahead. Its beam is turned downwards and focuses on the right side of the car (for cars that are driven on the right side of the street), illuminating the border of the road well and avoiding obfuscating other drivers. Its use in the rain is also recommended.

high beam

A long, taller beam that illuminates both sides strongly. This is the high beam, whose use is indicated on highways and roads without illumination and must be changed to low so as not to dazzle anyone if there are other vehicles on the road. Some cars even have a headlight assistant, technology capable of modulating the beam or lowering it when detecting a vehicle ahead or in the opposite direction.

Rapid activation is also allowed to warn drivers who are coming in the opposite direction of any danger or even to signal an overtaking. The light reaches about 100 meters and can have an even greater range, which depends on the technology applied.

Watch out

In the rain, forget the high lighthouse. “The low beam is designed for situations where traffic is heavy or has opposite traffic. Of course, if an empty road the high beam is there for that. Even in situations of high fog or heavy rain, the light from the high beam overshadows the water droplets. The impression is that it illuminates more, but the bass has a different effect and makes the visibility longer ”, explains Alessandro Rubio, engineer of the Vehicle Safety Technical Commission of SAE Brasil.


A misunderstood. The lighthouse has a more than clear use: it must be used in conditions of … fog. Its beam is low and wide to illuminate just below the mist layer. With that, it is possible to stay just below the fog and indicate the limits of the road.

Mile / Long Range Headlight

A beam even longer than the top. That said, the mile lighthouse cannot be used in any situation and is reserved for totally dark places with no one around. The mile is a tall lighthouse with a greater reach. You can use as long as you follow the same rules as the high beam.
