The L.E.T. Group is a family SME that was founded in 1967 as L.E.T. NV by Jozef Vandewalle. L.E.T. is both locally and internationally active in the field of headlight aiming and driving assistance systems. The first step in that direction was the development of the first "Luminoscopes" in 1980 for Belgian inspection stations.

Over the years the product range has grown and in the meantime L.E.T. grew to be a leading global supplier of adjustment systems for headlamps and driving assistance systems for the automotive industry.

In addition, the L.E.T. Group is active in the development, production, assembly and adjustment of electro-optical measuring devices.

Over the years, numerous precision tools and components have been developed and produced for a variety of industries, ranging from the automotive industry, to nuclear research centres and biomedical applications. To this end, the L.E.T. Group houses four major technologies: precision engineering - electronics - optics and (vision) software.


To meet the development and design of specific concepts, L.E.T. has its own equipment to develop prototype batches of printed circuit boards.

In addition, all necessary means are available for completing resistant testing, such as a simulation in bad weather conditions (heat, humidity, frost, …)

Precision Mechanics:

The workshop, equipped with lathes and milling machines, is used for the manufacture of prototypes and batches of specific components.


By means of the high-tech equipment for the manufacture of optical components (lenses, prisms, etc) a wide variety of optical applications based on mechatronics can be manufactured.
Similarly, the large number of Vision-applications can -by the usable know-how- be linked tot his.

Software abilities:

A team of professional software specialists ensures that all new development scan be used. In that context, the intelligent C-MOS camera (with digital signal processor) was developed. This is used both in the LUMINOSCOPE headlamp adjust systems as in other applications.


L.E.T. Automotive NV has several high-tech test areas :

  • Dust-free area -class 10000- for manufacture and assembly of precise and delicate equipment.

  • Dark Tunnel for the simulation of light patterns of headlights.

  • EMC-space for testing of equipment in an electromagnetic environment

This room can also be rented to third parties.

The L.E.T. Group employs about 70 people, among them many higly skilled people who work in R&D.
Some of our products are certified for various national inspection stations.
