Regarding flasher lights with LEDs with passive electronics In connection with these low powers, which differ significan tly from those of a bulb-based version, problems arise with the indicator failure check during operation on various traction vehicles. The indicator failure check required by legislation in the a rea of validity of the ECE R48 regulation must be guaranteed by suitable measures within the vehicle. The customer is responsible for this. In addition, further lighting functions are detected by some traction vehicles. This is a vehicle comfort function which is not required by legislation and does not release drivers from their obligati on to see for themselves that the lighting equipment is working. Here, too, faulty diagnosis can occur on account of the low power levels involved (instrument panel in the driver cab in dicates light failure although the function is working). Operation of the light with AC voltage or synchronised DC vo ltage is not permitted. The individual light functions may only be operated with a v ehicle fuse of max. 3A.
