Lamp driver system with improved redundancy

A lamp driver system for selectively driving a first lamp and a second lamp, the lamp driver system comprising:

• a first controller, the first controller selectively driving the first lamp and the second lamp;
• and
• a fault detector, the fault detector coupled to the first lamp and the second lamp to determine when a failure occurs in the first lamp or the second lamp, and wherein the fault detected is coupled to the first controller to determine when a failure occurs in the first controller;
• and
• a second controller, second controller selectively driving the first lamp and the second lamp when a failure occurs in the first controller.
