Scheinwerfer an: Mit Hauswand-Trick alle Auto-Lichter selbst checken

The ADAC recommends checking all vehicle lights using a simple house wall trick. By doing so, drivers can avoid dazzling other motorists or discovering faulty brake lights. To test the side lights, back up towards a wall and apply the brakes; a red light should appear on each side of the car in the rearview mirror. Similarly, for the brake lights, turn signal lights, fog lights, and parking lights, back up to the wall in reverse.

The number and location of illuminated points depend on the vehicle's equipment. When the parking lights are on, red turn signals will appear; if the fog lights are activated, additional red spots may be visible. To test the high beams, drive a short distance towards the wall with the car facing it, and the high beams will be visible from the front.

Daytime running lights are automatically activated when the engine is started and can be seen when the car is very close to the wall, provided the sun is not too bright. Front fog lights can be checked with the parking lights or daytime running lights engaged. If a person does not wish to perform the test themselves, they can utilize the free light testing service offered by the German Traffic Watch (DVW) and the Central Association of German Automotive Industries (ZDK) in October.

In October, auto repair shops across Germany will participate in the initiative, allowing interested individuals to search for nearby participating workshops using their postal code.
