I recently purchased some new 9007 bulbs for my 2002 cavalier and the link to the ones that I bought is:

And now when I put it in gear to activate the DRL's, they flicker ten times or so and then shut off plus the service light turns on. Also after I turn off the ignition and start it up a again the same problem happens again. If anyone thinks they know what the problem is please let me know or if anyone can fix the problem please let me know!!!
Thanks

Same thing happened to me, when one of my headlights burnt out.
I thought it was a DRL relay problem or something, but it wasnt.
One of your new 9007s is burnt out, more then likely the low beam.

You were right! I did some testing with the old bulbs. I put the old bulbs in and everything worked fine, then I took one out and the DRL's started acting up. Thank god the bubls had warranty and now i just wait till the new ones get shipped to me and i can have my super whites back.
Let this be a leasoned learned to me and everyone else...
