replace both with a kit at autozone 1st to see what happens .

in low beams or high or both?
that is caused by:
1: bad held lamp. old lamps can go dim.
swap left and right, if dim follows bulb, bingo weak bulb or wrong type bulb. buy matching blubs (same brand and P/n)
2: bad wiring to lamp. damaged wires, or connectors to same.
4: bad combo switch. (if low beams)
5: bad fuse or holder, corrosion , to either.
head lamp fuses. there are 2. left and right.
6: hackers, many hackers put in wrong lights. inspect it.

Could be a defective headlight relay, Located in the fuse block in engine compartment,

You may have a loose or corroded headlight ground to the body, the ground wires are in most GM attached to the body near the headlight under the hood. Check all the grounds you can see on the inside of the fender, tighten and clean the with a wire brush, also check the headlight connector for problems like corrosion or not fully seated to the headlight bulb.

Have you checked the switch?

You have a bad ground, look out by the battery for a bunch of black wires screwed to the body of the car, check that they have a clean and tight connection, scrap off any paint under the wires.
