HELLA showcased the K-LED Rebelution, an optical warning system light. The light emerges from a narrow, 8mm-high light band instead of through a dome. It generates a long-range warning signal. HELLA also makes the Optical Warning Mini Lightbars. The 10- or 16-in. bars generate an intensive 360° warning signal. Depending on the mounting variant, the flat roof bars can be mounted with a bracket or a magnet and are suitable for both 12- and 24-volt (V) systems, the company reported. HELLA also spotlighted the LED Rallye 4000 Metal and LED Rallye 3003 auxiliary headlights. Capable of wide and long-range illumination, the headlights, rated for 12 and 24 V, feature a cooling fin.
