Lamp functions

front marker light

Rear marker light

side marker light

The lamps have three functions: contour light front (white) , which highlights the contours of the vehicle at the front, improving its visibility for other road users, especially after dark and in difficult weather conditions ; contour light rear (red), which signals the presence of a vehicle behind, increasing safety and minimising the risk of collisions, and side marker light (orange) , which highlights the contours of the vehicle and improves its visibility, especially at night and in poor lighting conditions .

Tightness class

Marker lamps with IP67 tightness class are completely protected against dust ingress and resistant to short-term immersion in water (up to 1 meter depth for a maximum of 30 minutes). These properties make them ideal for use in harsh environments where there is dust, dirt and the risk of contact with water, such as in commercial vehicles, trailers, agricultural and construction machines. They ensure reliability and durability even in the most demanding working environments .

Approvals

Marker lamps with E9 approval meet the requirements of European safety and quality standards, which confirms their compliance with vehicle lighting regulations. The E9 certificate, awarded by Spain as the approval country, attests to the passing of rigorous technical tests, including light efficiency, durability and safety of use . Thanks to this approval, the lamps are approved for use in commercial vehicles, trailers and machines throughout the European Union, guaranteeing reliability in various operating conditions .

Marker lights are an essential part of the equipment of commercial vehicles, such as trailers, semi-trailers, agricultural and construction machines. Their main function is to improve the visibility of the vehicle both on the road and in the workplace, which significantly increases the safety of the driver and other road users . Marker lights play a key role in conditions of limited visibility, such as fog, night or heavy rainfall, helping other drivers and operators better assess the width and position of the vehicle. In the case of machines working on construction sites or in agricultural areas, appropriate light markings help avoid dangerous situations and collisions. Choosing high-quality marker lights is not only a matter of compliance with regulations, but also an investment in the durability and reliability of the equipment in demanding operating conditions.
