An indicator comprising a pointer (7) made of transparent material and turning about an axis concentric with the center of a dial (5) bearing the scale (6) of a measuring instrument. Near the center, the dial (5) is fitted with at least one LED (36, 37) at which the hub (11) of the pointer (7) presents an annular groove (32). The hub (11) comprises a truncated-cone-shaped reflecting surface (18) for reflecting along the hand (8) of the pointer (7) part of the light emitted by the LED (36, 37). The hub (11) also comprises a flat surface (19) for reflecting part of the light emitted by the LED (36, 37) and refracted by the conical surface (39) of a recess (38) in a portion of the groove (32). <IMAGE> |
