1. A light emitting circuit comprising:
a power source;
one or more light sources connected to an output of the power source;
a control circuit comprising a pulsed voltage source, and a control transistor configured to regulate a current through the one or more light sources based upon an output of the pulsed voltage source;
a monitor transistor comprising a gate connected to an output of the one or more light sources such that a voltage at the output of the one or more light sources controls an output of the monitor transistor; and
a monitor transistor detector connected to the output of the monitor transistor, the monitor transistor detector configured to monitor a state of the one or more light sources based upon a state of the output of the monitor transistor.
