A dome light is disclosed which utilizes a rotating knob with `on` and `off` positions to toggle between having either a halogen bulb on or a plurality of red LEDs on, or both off. Dual D-type flip-flops toggle the dome light between states in response the changes of the knob between the `on` and `off` positions. The plurality of red LEDs utilize at least one current regulator to maintain a constant level of illumination. When the halogen bulb is on, further rotation of the knob varies a potentiometer which controls the duty cycle created by a pulse width modulator. The pulse width modulator causes the halogen bulb to be on for portions of each cycle; the longer the `on` time during each cycle, the greater the apparent intensity of illumination by the halogen bulb.
