Emergency vehicles with flashing lights and sirens, buses with activated hazard lights at the bus stop, trucks with high beams on country roads - these are the eye-catchers in Miniatur Wunderland Hamburg. However, the attempt to modify vehicles for the Faller Car System is already challenging because the batteries of the vehicles do not provide sufficient voltage for white or blue LEDs or standard control electronics. With the FCS modules, vehicles for the Faller Car System can be retrofitted. The circuit boards are connected directly to the vehicle's battery. Different versions of the FCS module are available for various vehicle types. Please order LEDs separately.
