First, check that the battery connections are clean and not corroded. If not look for the ground wires that connect to the chassis. Check to see if any are corroded or loose. Finally if that has no effect, you have a short somewhere in your wiring. The easy way to isolate it is to pull the fuses for each device one by one and see if the dimming stops. The last one to cause the dimming is the problem. If it happens when you hit a bump it also might be a ground fault in the interior car grounds....good luck!
