Abstract
A system to verify the identity of modules within a stack light is disclosed. A sensor is mounted to a circuit board inserted within a housing of the module, and a target is mounted to or integrally formed in the housing. The sensor detects and generates a signal corresponding to the detected target. Different targets or locations for the target are provided for each housing. The module, a base for the stack light, or a remote controller in communication with the stack light identifies the housing in which the circuit board is mounted based on the feedback signal generated by detecting the target. At power-up, a routine may initiate a verification routine by which each module in the stack light determines the type of housing in which the circuit board for that module is located.
