The special shape of the integrated signal lamps means that the light is emitted optimally in every direction (to the sides and upwards). Continuous lights (with incandescent lamp or LED) and single-flash lights are available in five colors. As well as the continuous-light version, a flashing-light or all-round light version is also available. The LED versions of the integrated signal lamps offer a considerably longer endurance than the incandescent lamp versions. They all have the high degree of protection IP65 and are made of a material highly resistant to impact.
