1) Turn on parking lights, verify that all taillights are working. (Any that are blazing away much brighter than the others may be plugged in backwards and using their brake filament for the taillight circuit by mistake.)
2) Leave parking lights _on_, then have an assistant step on the brake while you watch the rear lights. Any bulbs that go out when they're supposed to get brighter have a bad ground connection.
If all the above checks out and the warning still occurs, get back to us.
