Abstract

The indicator light assembly (11) has a rectangular opaque mask (13) with three rings of transparent sectors (17a-21d) which may be individually illuminated. Each ring is broken into four portions. There are two further ring sectors (25a,b) to one side of the main pattern. Illumination is by LEDs (Light Emitting Diodes) (26).
