Its probably your switch housing. The contact points get corroded after a while, even quicker if the bike gets left outside in various weather conditions.
Either take your housing apart and clean the contact points, or buy a new housing.
Try flipping your switch to the high beam, and then lightly press on the low beam side but don't actually flip it back to low. My 03 is going to have this problem in the future, because my switch is already finicky.
