| Status Light
The Status Light can be used to detect if a true signal is being inputted. If so, a green light will turn on.
It can also be used to output a signal. It will transmit a high signal if it receives one or more high signals (acting as an OR gate). Otherwise, it will transmit a low signal (even if it has no inputs).
A status light with no inputs can be used as a source of a low signal for logic gates.
