1. A dual operation optical visibility and collision protection device for use in conjunction with a pivotable hatch of a motor vehicle, the device comprising:
- a sensor for detecting optical visibility and for detecting an obstacle in a pivoting range of the hatch, the sensor having an infrared transmitter and an infrared receiver;
a first control unit configured to output, in dependence on first sensor signals from the sensor, control commands for stopping an opening movement of the hatch;
a second control unit configured to output, in dependence on second sensor signals from the sensor, control commands for activating at least one of a headlight, taillight, or fog light of the motor vehicle;
wherein the sensor is configured to measure at least one of the reflectivity and transmission time of emitted and reflected infrared beams, determine a distance based on the reflected infrared beams, and transmit first sensor signals to the first control unit and second sensor signals to the second control unit based on the distance.
