I have a 2021 Equinox LS and installed Auxito LED headlight bulbs. You will need ballast resister . If it has HID headlights, the LED will not work. Auxito also has other LED bulbs for tail lights etc. Ballast resisters normally required unless bulb comes with internal resister. I have also used Sealight LED bulbs! And they are very good also.
Most are available on Amazon, and you can go to bulb mfg. website.
I have also installed LED headlights on my Ram pickup and Traverse, Auxito and Sealight.
