The headlights turn off because you have accidently hooked the stereo's power wire onto the headlight relay wire. When you turn on the stereo, there's not enough power left to run the headlight relay. Thus, no headlights. Re-wire the stereo.
Illumination is the ability to lighten the screen or darken the screen with the other dash lights on the vehicle. normally you will have two orange wires coming from the cars wiring harness one with a white stripe one without. The orange/white wire will make the stereo dim or brighten with the dash lights. the solid orange wire will dim/brighten the stereo with the headlights. so if it is night you will have the headlights on, when you turn the headlights on the stereo dims so the light from the stereo will not blind you at night. while the headlights are off the stereo will be bright so the stereo light will be visible in the daytime
Has it always been like this or not? If it is, then it is not really a problem. It is how the stereo was installed. An stereo can be installed to be turned on whether the engine is on or off. If the stereo cannot be turned off at all, then you have a problem with your stereo.

Check your fuses as this is very common when an after market stereo is installed.
It is important to know what is going on inside of a vehicle. The headlights dim when a stereo is turned on or turned up because power is being drawn away from the lights to the stereo.
If it is an aftermarket stereo then i would say that the installer tied into the dashboard illumination or headlight power wire for 12 volt power for the stereo.

On 1984-1989 Corvette, the dash top grilles only housed speakers if the car was not fitted with Bose stereo, about 10% of production. TOM

I'm guessing your stereo is aftermarket. If so, then whoever installed it did it wrong or tried something tricky.
