Abstract
An automobile gauge in which the needle thereof is brightened so that the ability with which the driver can see and confirm the position of the needle is enhanced. A pigmented layer is formed on the indicator portion of the needle. Bulbs and a light-guiding plate disposed on the reverse surface of a dial, or a light emitting element provided at the back of the needle introduces light so as to brighten the needle. Because the indicator portion of the needle is shaped into a substantially long and slender cylinder, the light irradiated and guided into the indicator portion advances toward the end of the indicator portion while the total reflection thereof is repeated. Most of the irradiated light reaches the end of the indicator portion because very little of the irradiated light dissipates outside the needle. The entire indicator portion can be thereby brightened uniformly.
