The movable lights can be mounted at an angle of up to 5 degrees using a base. This ensures universal use on nearly all cabs of construction vehicles or heavy-duty tractors, superstructures, trailers, semitrailers, etc. Four bulbs blinking in sequence create the rotating light effect. These double rotating lights are controlled via SMD blinking electronics and a free switch cable at the receiver. Contents: 2 rotating lights (diameter 14.5 mm, height 25 mm with base) as well as a ready-to-connect circuit board with shrink tubing (dimensions: 37 x 30 x 5 mm) and Graupner-J/R connection cable.
