WESEM quality is based on independent design of our products in which we have many years of experience as we have been focusing on our individual solutions since our very beginning in the 1970s. By means of these designs we exactly meet the needs of our clients and we can provide them with customized products.
At the beginning, all our lamps are designed as a 3D model that is then tested by means of virtual thermal and photometric analyses. At this stage, the project can be developed and improved without launching expensive manufacturing processes.
Then it is time for prototyping. Spatial models are produced in our workshop or by means of 3D printers. After performing complex analyses of our models we develop the manufacturing technology with the use of the vast set of CNC machine tools.
Individual design allows us to match the product with its particular application in a flexible way and, most importantly, it ensures that high quality standards are maintained.
We say that WESEM is a European manufacturer of lighting used in the automotive industry. Thus, it indicates who we are not. WESEM does not import finished lamps and it is not an assembly plant of prefabricated products manufactured by others. We design our products by ourselves and manufacture them in Poland.
We manufacture almost all our elements by ourselves. In the WESEM injection room we produce parts made of plastics. Metal elements are produced in the cold work processing department. Moreover, certain details are treated with surface processing. In particular, they are galvanized, coated with powder and sprayed with the use of the method of thin layers.
The innovative machinery park provides manufacturing repeatability and the WESEM work cells producing lamps are flexible. Thus, we can produce both large and limited series of our products in an efficient and profitable way.
Functionally designed, self-manufactured and appropriately protected WESEM lamps can be used for a long time in an efficient way. Their reliability is confirmed by detailed tests performed both at various stages of production and on finished lamps.
Quality is our priority, that is why we test and analyze our products at every stage of production. We virtually test 3D models already at the designing stage; tests are also performed during the manufacturing process. Also finished products are tested in our laboratories.
Optical parameters of lamps are checked in the photometric laboratory equipped with two light paths: for 3.16 m long signaling lamps and for 25 m headlights. We also perform ageing tests, checking the resistance of our lamps to vibrations, UV radiation, corrosion, low and high temperatures and their sudden changes.
In our research we focus on the areas in which we have to be sure that the product meets requirements of our customers. Moreover, we perform complex periodical tests. Detailed testing allows us to guarantee total lamp repeatability and their highest quality that gives our customers assurance when it comes to the reliability of our products – WESEM lamps are manufactured and widely examined in order to meet customers’ needs in all conditions.
Since 1977 the WESEM company has provided lighting for agricultural machinery and vehicles. The high quality of WESEM’s lamps is guaranteed by a qualified staff of specialists, a modern machinery park, the R&D department and a fully equipped measurement and testing laboratory.
WESEM’s products, designed and produced in Poland, successfully combine modern design trends with the latest technical solutions. That is why the products have been present on European, Asian and American markets for years. Moreover, an excellent proportion between quality and price causes that WESEM’s lamps are used by numerous OEM manufacturers as well as by wholesalers of spare parts from many corners of the world.
Traditionally, the WESEM company places emphasis on its customers’ needs. Flexibility and innovation help the company to meet even the most complex requirements of its clients. Dedicated products are created for both regular and new customers.

WESEM has extended its product range by adding a manoeuvring lamp to its CRP1 product family. The lamp is designed to provide lighting to the sides of a vehicle. Adding manoeuvring lamps to your vehicle, thus ensuring better visibility, helps avoid accidents or collisions with obstacles as well as improving comfort while parking or reversing.
We did it! We brought to market a family of powerful CRP3 lamps, specially dedicated for vehicles and machines used in forest operations, on construction sites and in mining operations. Robust and durable, CRP3 lamps are intended for service in extreme conditions.
Summer holidays are a time when we go away, often pursuing active recreation.
