I have a weird prolem with my driverside headlight. When I unlock the car the headlight will turn on but when the day time running lights are on or if i manualy turn on the lights the headlight wont turn on. If I run the highbeams the light works fine. I don't understand what could be causing it. I haven't driven at night in a few days for this reason. Any help will be great. Thanks.

Low beam element in the drivers side light is burnt out. New 9007 should fix you right up

Might want to replace both sides while you are at it, the other one is likely close to dying as well - just keep the still working one as an emergency spare.

9007 bulbs (What the Cobalt uses), are a dual beam bulb. They have two filaments, one for the high and the other for low contained in a single bulb.

Update!!!
Thanks for the help guys. Before I bought a new bulb i went ahead and switched the one that was working properly to the apposite side. The lowbeam work fine so i plugged the new bulb in the passenger side and it worked for a few minutes and then went out. ???? This was not the side that was having the problem. It was a 12 dollar bulb by the way. Maybe just bad luck?
