Hah, I have this problem too.
Usual suspects are license plate bulbs or brake lights with poor contact. Like the poster above said, sand the contacts a bit. Some have reported success by not screwing the bulbs all the way in for the brakes -- leave a quarter turn or half turn of thread unthreaded and supposedly this allows for better contact.
Also, interior bulbs will never give you an error so that narrows your search considerably.
