This the 3rd time I have had to replace headlights, brake lights too! The headlight was going on and off while driving at night, took and had the lamps replaced, hasn't done it since. Lamps need replacing it seems to me a lot. I still have a reverse light that is out.

Driver's side headlight will go out suddenly while driving. Have replaced the headlight numerous times! This is a GM electrical issue that needs to be addressed by the manufacturer. It appears that others have had the same issue.
