What changes are still to come about with respect to the “Headlight Test Guideline”, which will enter into force on 1 January 2017? The MLT 3000 adjustment unit from MAHA allows workshops and testing organisations to also, in any case, lawfully carry out headlight inspections as part of the PTI thanks to ultra-modern measuring technology.

Haldenwang, 24 March 2016. What many people long since considered necessary has been confirmed for just under two years now: the new PTI Headlight Test Guideline will become binding from 1 January 2017 onwards. The legislator is thereby providing detailed information on how vehicle-mounted lighting systems, which have become increasingly complex, have to be tested and adjusted, and particularly on the condition of test stations too. This is because the guideline is being used to pursue a fundamental objective: improving road safety. If you consider the results of the 2014/2015 Light Test Weeks, for example, you’ll notice with alarm that almost every third vehicle has a lighting defect. From headlights that are set too high, over headlights that dazzle oncoming traffic, to vehicles that are all but “blind”, the threat to road users is indeed serious.

Identifying and correcting incorrectly set headlights is an important task for workshops and testing organisations if they are to improve road safety. With the MLT 3000, MAHA is providing an innovative technology for this very purpose, since the unit records the headlight image using a high-performance CMOS camera and precisely digitises the results. Within fractions of a second, a powerful microprocessor evaluates the light/dark boundary, for example, illustrates its development on the colour display and – at the same time – establishes the relationship to country or manufacturer-specific requirements in real time. Thanks to the practical, optional track system, the unit only needs to be aligned to the vehicle’s longitudinal axis once – an aspect that is both convenient and saves time.

But now for the highlight of the MLT 3000: the unit’s self-levelling function compensates for unevenness in the floor. A position sensor records the unit’s angle of inclination and the software automatically compensates for any deviations from the horizontal plane when calculating the headlight position. This aspect is an integral part of the new guideline and the MLT 3000’s function is thus highly significant, since unevenness in the floor of just a few millimetres has a major influence on the headlight setting. Levelling plates from MAHA (“MLP 2000”) can be used to meet the legal requirements placed on the vehicle support surface at the same time. They are a time and cost-saving alternative to time-consuming foundation work.

The flexibly adjustable menu, which can be adapted to a wide range of requirements set by car manufacturers, legal specifications and country specifications, and the 7” colour touch display ensure user-friendly operation. The user is guided through the menu in a self-explanatory manner and receives visual support during the test procedure. The optional visual adjustment aid on the front of the unit makes for convenient and correct headlight adjustment using coloured LED indicators.
All of this ensures maximum operating comfort during the test procedure and perfect adjustment.

The guideline has been a hot topic of discussion ever since it was published in May 2014, and amendments, adaptations and modifications are expected this year. But the MLT 3000 offers pioneering technologies that will be capable even in the future of lawfully measuring and precisely adjusting ultra-modern lighting systems and light assistance functions regardless of the manufacturer or model. Maximum flexibility and the possibility of software updates means that car dealerships, workshops and testing organisations are excellently equipped with the MLT 3000 – and that’s a dead cert.
