Lighting

Lighting is the foundation of safe and legally compliant operation in the truck and trailer industry. Whether it concerns a semi-trailer travelling on a European motorway at night, an articulated vehicle delivered after a complete body build, or a working vehicle deployed in a port environment, every component of the lighting installation must comply with the applicable homologation standards. For professional workshops, trailer builders, bodybuilders and transport companies operating their own maintenance facility, understanding these regulations is the starting point for all work involving truck lighting and trailer light 24V systems.
The European ECE framework defines the central requirements for lighting on heavy commercial vehicles and trailers. ECE R48 covers the installation requirements for all lighting units on a vehicle, including which lights are mandatory, their required positions, the minimum angles of visibility, and the photometric performance each lighting function must achieve. Without compliance with ECE R48, a vehicle cannot be admitted to public roads in Europe. ECE R7 specifically regulates the requirements for position lights and marker lights, including the side marker lights that are mandatory on semi-trailers and wider trailers. ECE R65 applies to rotating beacon lights and warning lighting for special vehicles and abnormal loads. In addition to these functional standards, ECE R10 governs electromagnetic compatibility, which is relevant for LED lighting components integrated into modern vehicle electronics. The product range on this page covers components that align with these regulatory frameworks, for both 12V and 24V installations.
The lighting range at dekoff.com is organised into multiple subcategories, each addressing a specific part of the vehicle lighting installation. Rear lights are the most critical units at the back of a trailer or semi-trailer. They combine multiple lighting functions in a single housing: stop light, tail light, direction indicator, reversing light, fog light, and in many cases number plate lighting. The exact configuration and positioning is defined by ECE R48 and determines whether a vehicle meets the European requirements for ECE approved trailer lamp during inspection or roadside checks.
Headlights for trucks must produce a precisely shaped light beam that does not dazzle oncoming traffic while optimally illuminating the road ahead. Modern LED headlights are available in common fitting sizes including H1, H3, H4 and H7, and are designed for both 12V and 24V supply voltages. Lamp sets in this range are assembled for direct use in the workshop and provide the correct combination of fitting, power and voltage for the 24V system standard in heavy transport.
Width marking lights and side markers are mandatory on vehicles exceeding a certain width and form an essential element of semi-trailer visibility in traffic. Marker lights must comply with specific colour requirements: white at the front, red at the rear and amber on the sides. Reflectors supplement active lighting with passive visibility. They return light to its source without requiring an electrical connection and are legally required at fixed positions on the sides and rear of semi-trailers and trailers. Both red and amber reflectors in various sizes are included in this range, suited to standard mounting points in trailer construction.
Lamp holders are the connecting link between the lighting unit and the electrical installation. In a professional workshop environment, selecting the correct fitting type and material determines whether a lighting point continues to function reliably under the demanding conditions of vibration, moisture and temperature variation. Replacement lenses make it possible to replace only the damaged optical component without removing the entire lighting assembly, saving considerable time and cost in daily maintenance.
Number plate lighting is a legally required component that directly determines whether a vehicle is admitted to public roads. Inspection lamps are portable work lights for the workshop, essential when working in difficult-to-access locations such as under a semi-trailer or behind a cab. Warning signalling equipment such as warning triangles completes the range for situations where vehicles are temporarily stationary at the roadside and visibility for other road users is legally required.
Dekoff.com supplies this complete range of truck lighting and semi-trailer light products as a B2B webshop to truck workshops, trailer builders, bodybuilders, semi-trailer specialists, wholesalers and transport companies with their own workshop. The range is tailored to the 24V systems standard in the professional transport sector, without overlooking 12V applications for lighter vehicles and trailers. All components are selected for compliance with the applicable ECE standards, ensuring that every lighting point sourced through dekoff.com forms a reliable basis for a legally compliant and safe lighting installation.
