Abstract

A pointer instrument for a motor vehicle includes a pointer drive for deflecting a carrier body. A pointer which is visible in an indication is provided on the carrier body. An optical waveguide element is arranged on that side of the carrier body which is remote from an observer. Light from at least one light source is introduced into the optical waveguide element which extends along the movement path of the pointer. Light emerging from the optical waveguide element enters into the pointer and/or the carrier body, and the pointer is formed such that it is illuminated by light emerging from the optical waveguide element.
