Abstract

A recognition light includes a reflector having an axis and first and second annular semi-parabolic reflective surfaces (40, 42) which have respective focal points axially spaced apart from one another, and first and second annular lamps (34, 36) respectively disposed at the focal points. A cover (14) surrounds the reflector and lamps and includes a lens (20) for focusing the light along a plane perpendicular to the axis of the reflector, the lens including first and second Fresnel lens portions each including a convex lens and a prism lens, the convex lenses being disposed adjacent one another and transaxially aligned with the first and second lamps, respectively. A light detector detects light emitted from at least one of the lamps, a monitor circuit provides a fail signal when a characteristic of the light output of at least one of the lamps does not satisfy a specified criteria, and a control circuit first activates the first lamp and then the second lamp in response to receipt of the fail signal of the monitor circuit.
