Perhaps a weak battery? How old is battery?
The lights dim when the air conditioning turns on because both appliances require a lot of electricity to function. When the air conditioning unit starts up, it draws a sudden surge of power, causing a temporary drop in voltage that can make the lights dim momentarily.
It's the surge of power that's decreasing the voltage. Nothing to worry about.
If you know where to change the odometer/tripmeter display... Instead of pushing that control, turn it counter-/clockwise to dim/brighten the dash lights.
Dim All the Lights was created in 1995.
When the bass hits in your car the headlights will dim if you have enough power. Installing a capacitor (the capacitor stores power and creates a buffer) absorbs this surge and your headlights don't dim. Not unlike a capcitor in your home airconditioner. Without a capacitor, your house lights would dim when it turned on.
You should dim your lights as soon as you see their lights.
my dash lights blink and dim when braking/found t this was a ticoverter that rusted
How dim? There are several possible answers. First, the output of the light coil is directly related to the engine rpm. Second, if the regulator/rectifier is not functioning properly, the lights can be dim. Third, if you have a poor ground connection the lights will be dim.
when you see there lights you should dim yours

realign the head lights, check battery termninals
Possibly a bad alternator (the system is not charging the battery).
