Also cluster lights come on and then get dim when head light switch is turned on
The basic problem is too much resistance in a circuit.
You have to figure out which one and where the resistance or short is.
You can take the fuses out one at a time or all at once to see which circuit is pulling too much current.
It could be a faulty ground somewhere and the lights are grounding thru the wrong circuit. Or something shorted together and pulling current thru the wrong circuit. Like the headlights running off the dash light circuit.
You may need a book with wiring diagrams to know what to check.
SOURCE: 2000 CHEVY IMPALA WHEN AIRBAG LIGHT IS ON-NO TURN SIGNAL
The only thing I can think of that would explain your problem is a faulty ignition switch.
SOURCE: 2003 Chevy Impala - radio, instrument
There are two possible cause of dim display.
On the deluxe trim level of the Impala the is light sensor. When the sensor mis-calibrated the light will not be at the level you want.
As a test,use a small flash light and aim to the sensor and see is the circuit act according it.
====
The dimmer light is a VERY CHEAP component. I will glow it out with compress air 1st. Turn the dial back and forth 20-30 time in rapid motion will help remove unwanted carbon,
===
Use a eletrical contact cleaner to clean all contacts.
===
Is the headlight in OEM specification?
After market headlights may draw more amperage and cause low power for smaller bulbs.
