I have a 68 Camaro with a tic toc tach and the lights in the tach are dim. The speedo is fine. Anybody have an answer for the dim lights?

 

Possibly the wrong bulbs. Do they get dimmer and brighter as you turn the ****? If they do, then you need to replace them with a brighter bulb. A lot of bulbs look the same, but they have different brightness, just like household bulbs.

 

could be wrong bulbs, halfway burnt out bulbs or there could be a lot of dust behind there after all these years blocking the light
