A lighting system is disclosed. The lighting system includes a first selectively actuated light module that emits light having a first polarization orientation. A second selectively actuated light module emits light having a second polarization orientation that is orthogonal to the first polarization orientation. A first combining element combines and directs light from the first and second light modules into an optical path. A first polarization alignment element aligns the polarization of light from the first combining element to a predetermined polarization orientation. The first and second light modules are selectively actuated to ensure that light having the predetermined polarization orientation is substantially constantly emitted when desired.
