C3 Speedometer light.

[MAJohnson]

Hello, I have a 1976 and the light for the speedometer is acting up. When I turn on the lights it will work fine, but when I speed up while driving it will dim out. Only the speedometer light dims out, the rest stay working fine. If I rotate the headlight switch to turn on the interior light the speedometer light comes back on at full power, but will dim after I turn the interior light off. Any info on what the problem might be would be appreciated!

Try removing and changing the light bulb and inspecting the socket. All the dash lights are in a parallel circuit, so it's likely to be just the one bulb or socket.
