ABSTRACT:
Disclosed is an indicator which includes a scale plate having a ground color, a pointer rotatably mounted on the scale plate and indicia such as numerals and scales arranged on the scale plate for indicating a specific value in cooperation with the pointer. The pointer includes an upper surface on which a fluorescent part having fluorescent brightener therein is formed, and the area of the fluorescent part of the pointer is smaller than that of the upper surface of the pointer. Each of the indicia has a contour defined by a normal ink having a different color from the ground color of the scale plate and a fluorescent part having fluorescent brightener therein formed in the contour of each indicia. The area of the fluorescent part of the indicia is smaller than that of the indicia. This indicator further includes an unltraviolet light source for illuminating the fluorescent parts of the pointer and the indicia so as to fluoresce only when the ultraviolet light source is turned on, whereby suppressing that the indicia and pointer become too bright and distracting for a driver when illuminated by the ultraviolet light source.
