An indicator gauge is disclosed, which comprises a housing; a dial board installed in the housing; and a pointer arranged in such a manner that an elongate pointing portion moves over a front face of the dial board. A narrow band of fluorescent substance is centrally located longitudinally along the full length of the pointing portion. The narrow band is bordered on each side along the full length by remaining areas of the pointing portion free of any fluorescent substance to create a contrasting appearance for maintaining a distinction between the band and indicia on the dial board when subject to ultraviolet light. An ultraviolet lamp is arranged in front of the dial board and the pointer to excite and thus cause the fluorescent part of the pointer to emit visible light.
