In contrast to conventional halogen light solutions, they stay lit up to three times longer and are thus recommended for drivers who are often on the road. The light sources are intended for all lamps on the exterior of the vehicle. Whether for parking, position, fog, license plate, indicator or brake lighting.
Mercury vapor lamps (HQL) are often used as light sources for street and factory lighting because of the low investment costs. They need a ballast but not an igniter. Because of their low efficiency, mercury vapor lamps consume much more electrical energy than metal halide lamps or high-pressure sodium lamps for example to achieve a certain quantity of light.
