Mining Light Circuit
The pilot lamp which is installed in scene can helps the driver to determine the situation behind car. The phototransistor is used as optical signal sensor, when light shines on the photodiodor, relay J0 closes and one of the normal-open contact close too, if the green light open, it means that there is no obstacle behind car. If there are some obstacles block the light, relay J0 does not close, red light opens. (View)
