Abstract:
1. A current control module for use in a vehicle having a marker or tail lamp, a stop lamp, a left turn signal and a right turn signal, said current control module comprising: a circuit board; a plurality of wires coupled to the circuit board, each wire of said plurality of wires corresponding to one of said marker or tail lamp, stop lamp, left turn signal or right turn signal; a plurality of current monitoring circuits on said circuit board, each one of said plurality of current monitoring circuits corresponding to one wire of said plurality of wires, each current monitoring circuit including: a current sense resistor; a current sense amplifier for producing an output voltage that is a product of amplifier gain and voltage drop across the current sense resistor; a differential voltage comparator for comparing the output voltage to a reference voltage and turning off when the output voltage exceeds the reference voltage; a transistor coupled to the differential voltage comparator for turning off and preventing current from being delivered to a corresponding one of said marker or tail lamp, stop lamp, left turn signal or right turn signal.
