Abstract

A pull-out light tube assembly is mounted in an equipment component such as a component that is mounted in an equipment rack. The light tube assembly includes a light tube received within a bushing. The light tube can be pulled out from the bushing and retracted into the bushing. The assembly includes a mechanism for self-centering the light tube within the bushing when the light tube is retracted into the bushing. A guide channel formed in the bushing receives and guides a guide pin formed in the light tube to a centered position. The guide channel may be a V-shaped groove with a receptacle and detent formed at an end thereof to secure the guide pin in a centered position. The mechanism for self-centering maintains a logo formed at a front end of the light tube in a properly oriented position when the light tube is retracted within the bushing.
