Hey Alex,

Dear it is quite easy, you can use 1 photo sensor and 2 bulbs one green and other one red, just for prototype. The sensor is installed on the ground and the bulbs on the ceiling level. Supposed when the Car is parked, then the sensor became below the car and sensor give signals to the circuit, supposed first the green bulb is light up but when sensor give signals than green bulb is light down and red start light up's and your parking system is designed.
