ABSTRACT:
An indicator pointer is arranged between a dial board and a viewing window so as to swingably move over the face of the dial board in response to rotation of a spindle of a movement of the indicator gauge. Illuminating means such as a light emitting diode (LED) is disposed in the pointer to illuminate a relatively large portion of the pointer. Opaque paint is coated on the front surface of the pointer to conceal the illuminating means.
