Abstract

A B S T R A C T

Diametrically pivotal disk is electromagnetically driven to display bright (ON) or dark (OFF) sides and has an optic fibre rearward of the disk. The disk is provided with a cut out to allow emission from the fibre in the ON position of the disk and the disk is shaped to prevent emission of light from the fibre in the OFF position of the disk.
