Your headlights turn off when you turn the high beams on because you have a defective switch. You need to have a mechanic replace the high beams switch. It is a simple replacement.
Because the lights are so bright
To find the cause of the low beams not working, start with the bulb to make sure both are ok. Check the dimmer switch, and the wiring from the switch to the headlights.
Because there are two different bulbs for the hi-beams and lo-beams
Your headlights may not dim because you don't have dimmer lights. Dimmer lights can blow and leave you with just the high beams.
The headlights are on two different fuses. The high beams are on one fuse and the low beams are on another fuse. The fuse for the low beams may need to be changed.

Well, assuming that you are talking about headlights, the low beams are the dimmest settings for the drive headlights, while high beams are the brightest setting.
you will need to get the wiring diagram and follow the schematics,but I believe the high beams generate their power from the mult-function switch
one or more headlights don't work but others do.none of the headlights will work.high beams work but low beams don't and vice versa.lights flicker and sometimes go dim.
Answer: on the turning signal switch turn the handle forward for headlights. high beams pull in to flash. push out for high beams to stay on.
Not uncommon in that model; apparently the wiring harness is weak at the low-beam wire; read more in the forum below. gminsidenews.com/forums/f53/1997-pontiac-sunfire-headlights-40665/
