The car headlights

According to the road code, the car’s headlights, both the front and rear, serve to see and be seen. Therefore, it is essential that they are subject to periodic checks in case some lamps run off or does not illuminate as supposed.

In the case of rear headlamps, they must be seen at 30 metres and require less care. The worst that can happen is a bulb to fuse and be required to replace it.

The math’s that has to be made is as follows: you must subtract 5cm from the measurement of the height of the headlamp to the ground, which is equivalent to 5 meters away, i.e., 1% inclination of the headlamp.
  3. Then make a mark on the wall in a horizontal line at a height of 61 centimeters.
  4. Turn on the headlights and make sure that the light projected beam on the wall is on the horizontal line you marked.
