ABSTRACT:
An LED display device has an indicator having a housing. The housing has at least one incident portion which receives light from at least one LED. The incident portion has a reflection surface at its inside surface. LEDs emit light from one side or one longitudinal end of the incident portion. A refraction plate may be provided to direct emission of the incident light for viewing by a user.
