The increasing complexity of high-tech components in modern vehicles requires flexible diagnostic solutions. Successful and (from the workshop’s point of view) profitable vehicle repairs are hardly possible without fast vehicle identification, reliable fault diagnostics, comprehensive provision of data and parts, and professional support. This is where professional diagnostic units, for example the latest devices from the HELLA Gutmann Solutions mega macs series, come into play. These communicate directly with the vehicle control unit, evaluate fault codes, provide repair information, and guide you step-by-step through camera and matrix headlamp calibration procedures, and much more.

The matrix LED high beam must be re-calibrated in certain situations, for example following installation/removal of the headlamp, replacement of the windscreen, wheel alignment of the rear axle, or installation/removal of the front camera. Following adjustment of the low beam, the front camera system must also be re-calibrated, as the high beam loses its learning values in this case.

Correctly adjusted headlamps are an absolute must on the road, and should therefore be regularly measured and re-adjusted by a workshop as required. This is the only way to ensure visibility and safety. Until recently, this test was carried out using the so-called "10-meter wall". With this measuring method, a vehicle is placed in front of a light-coloured wall, which has certain markings on it, at a distance of 10 m. The headlamps are then checked or adjusted based on these markings.

This may still be a statutory test method today, but in the format described, it’s best used for checking the lights on agricultural or special vehicles, which have the headlamps installed in a high position. Because the disadvantages of the "10-metre wall" are obvious: a relatively large, light and open wall, and therefore a lot of space, is required, both of which are often not available, especially in smaller workshops. Furthermore, today's modern lighting systems place significantly higher demands on the measuring process. Nowadays, checking and adjusting headlamps is almost exclusively carried out using modern beamsetters (SEG for short). Such devices allow the light distribution to be checked more quickly and with greater flexibility.

The increasing prevalence and further development of new headlamp technologies and light assistance systems also leads to greater requirements when it comes to inspecting and adjusting headlamps. This not only applies to the beamsetters, but also the measurement environment. A directive was created in Germany to ensure greater precision when measuring and adjusting headlamps. It contains precise information for correctly setting up a standardised headlamp adjustment station.
