When I was driving to work today I got stuck in traffic and noticed that my odometer reading will brighten and dim. I had my headlights on so the panel lights were illuminated. Anyway, would dim and brighten like if you turn the lights on and off. It was only the odometer that appeared to dim. I couldn't tell if the dash dimmed or not. Any ideas?
Odometer dims/brightens

I'm thinking if your AC was kicking on and off, or if you have after an aftermarket stereo and amp (pulling lots of power) would probably cause that. I've had it happen in my truck all the time. Other possibilities... the bulb may be getting ready to burn out (if non digital) or the alternator is not keeping up with your current power demands.
Did the light fluctuate in sync. with your RPMs??

Nope, A/C was off. It really didn't fluctuate with any pattern. I would start to go again from a stop and it would do it, hit the brake it would do it or just plain driving it would do it. Once traffic let up I was cruising in 5th at about 2200 RPM and it was still doing it.
We're talking about a digital readout right??
So power output of the engine/alternator has no effect on the displays brightness?? If that's the case then I would guess an illumination bulb might be on it's way out.

It could be just a loose wire? All I know is when mine would do it, I had the stereo up and the amp pulled so much power that the factory alternator could not compensate and the dash lights and head lights would dim with every hit of the subwoofers
