A headlamp flasher control allows the opening/closing of doors as well as the actuation of other devices. By this means it is no more necessary to carry along transmitters or other utensils as the impulse is given by the signal of the cars´ headlamp flasher. Headlamp flasher controls are already in use for the opening/closing of doors in garages for example.

The sensor of the headlamp flasher is installed on the exterior of the door and is linked with the control unit on the interior side. The control unit accepts the light signal and passes the signal on to the povided receiver 868 MHz. By this way the headlamp flasher control can control doors or other devices.
