Make turning safer with the flashing module for side marker lights. One side of the side marker lamps is permanently lit and the other side flashes synchronously with the direction indicator. New vehicles of classes M and N must be equipped with additional flashing modules that give the signal of the direction indicator synchronously to the side marker lamps with the addition of ECE-R48 regulation 6 or StVZO §54 of 2019. Cyclists and pedestrians are to be warned more thoroughly when changing direction and the rate of fatal accidents caused by this is to be significantly reduced. The housing of the module is corrosion-protected, lacquered in black and has sealed cable routing. 2 flashing modules are required for one vehicle.
