Abstract
A first light reflecting surface is formed at either the back side of a hub section of a transparent pointer or an hole formed in a transparent dial board and a second light reflecting surface is formed on a front side of the hub section of the pointer. Light rays transmitting entirely within the dial board in a direction parallel to the longer dimensions of the dial board are reflected toward the second light reflecting surface by the first light reflecting surface and then reflected toward the pointing section of the pointer by the second light reflecting surface to illuminate the pointer.
