Do you have a dimmer for interior lamps? Like a rheostat, a little wheel that you turn up or down to brighten or dim interior lamps. Usually the instrument cluster lamps brighten and dim the same way.
Can you brighten and dim the other interior lamps?

Probably just a couple bad bulbs.

You don't say if it's "just" the dash lights, or if other lights do it as well. Try turning on a dome light and see if the dome light does it along with the dash lights. Do you notice your headlights doing this as well? These are just troubleshooting steps. If multiple light sources (dome, headlight, etc.) do it, then it's most likely a voltage regulator issue.

most dash lights you can brighten or dim by the light switch.

is there a light adjustment switch on dash somewhere like a dimmer switch dim or brighten lights to your choice

you need a new altinator if ur head lights dim and u are loosing power!!

Sounds like an internal cluster issue.

do you have any kind of entertainment systems hooked up to the battery for instance the subwoofers in my car constantly make my lights dim and brighten if i have them loud enough
