Headlight range adjustment

Is your vehicle fitted with a xenon or LED headlight system? We can check whether it complies with limit values relating to dipped beams.

If dipped-beam headlights are fitted with light source elements which exceed a luminous flux of 2000 lumens, the vehicle must be provided with an automatic headlight adjustment system.

In some circumstances, it is possible that the suspension of the vehicle alone is enough to ensure compliance with the limits. After a successful check, we will be happy to issue you with the confirmation or conformity document required for approval.
