Bright Lights/Head Lights problem

Okay, when I turn my lights on (sometimes even the parking lights) The bright lights gauge comes on on my gauge cluster. Well even when the lights are fully on, when I go out to check... no bright lights at all... instead just the normal headlights are on... The LT1 style it's (Normal - Bright...(nose)...Bright - Normal) right? Well the gauge say's they're on but they're not... and when I pull the switch to turn them off, I can pull as far back as I want to but they won't turn off!... The switch doesn't click or anything it just pulls back and reclines to its normal position. Well while it register's the brightlights as being on, I cannot drive with my fog/driving lights with them registered as on... meaning I'm stuck with just normal headlights. What could be the issue here? Is it probably just a faulty brightlight switch?
