Claim 11:
12. A method, comprising:
generating a pulse-width modulated supply signal;
transmitting the pulse-width modulated supply signal to a subset of lighting devices of a plurality of lighting devices, each lighting device in the subset of lighting devices receiving the same pulse-width modulated supply signal;
generating a control signal for each lighting device in the subset of lighting devices, the control signal for each lighting device being independently controlled with respect to the pulse-width modulated supply signal; and
individually coupling and decoupling each lighting device in the subset of lighting devices from the pulse-width modulated supply signal as a function of the control signal to individually adjust a brightness of each lighting device in the subset of lighting devices.
