I’m gonna keep this simple.

Driver side light turns on. The right light turns on only when I click the knob all the way to the right. Once I do that the left light turns off.

at no time will both day time lights be on at the same time.

Are these stock halogen lights, or did someone modify them in any way?

Left light went out. I changed the bulb and then this started happening. The light I put in is way brighter. It may be a halogen.

Help will be difficult if it's not known how the vehicle is equipped. Fuses are likely good since the lights work (at times). Check the headlight relays and find out if they're working properly.

Since you just replaced the bulb . . replace the other also.
Or. . try swapping bulbs and note any results.
