C5 headlights
So I bought a c5 and it has that motor gear that grinds (just ordered it but with all this virus might be delayed) basically I want to know how the car/headlights know it’s dark and make them pop up? Or is there a way that I can put them down while driving? (Want to shut them down when I go to my job parking spot) kind of embarrassing having a super clean car with a loud grinding noise for 5 seconds lol

Mine doesn't pop up so may be able to go into DIC settings and change that, not sure or pull the fuse. Look on under hood fuse panel for description or U maybe able to unplug from wiring harness.
Just looked in manual and go to option and follow this info. I think you want twlight off.
Twilight (Optional in United States,
Standard in Canada)
Press the OPTIONS button until TWILIGHT-OFF
appears on the display, then use the RESET button to
page through the following selections:
' TWILIGHT - ON
TWILIGHT - OFF
If you choose TWILIGHT - ON, press the OPTIONS
button again to display DELAY TIME 1 2 in the DIC. Use
the OPTIONS button to switch between delay time
1 and 2. You can increase the delay time by pressing
button 1 (1 FUEL) or decrease the time by pressing
button 2 (2 GAGE§). Each bar is equal to 12 seconds.

There's a light sensor in the dash. GM has been doing that for decades. That's how it knows when it's dark.
Turn off twilight sentenel as above and it won't auto-pop up anymore.
