what does it mean when the "lamp out" pops up on my dash? my clutch wont activat on 2002 Dodge Ram 1500

no matter how far i push the clutch in, i am not able to put the truck in gear. any help??? is there a spot where i can put fluid? because i hear a hissing noise when i push the clutch in as if the line has busted or something.
