How do you get the headlight switch knob off?

I know this was posted many times and of course I didn't commit it to memory. Search is down so I'm going to need someone to share their wisdom with me. In addition to this question, can the dash bezel piece be replaced without puling the whole gage assembly out? It looks to me like the front screws can be removed from the bezel and then the attaching screws on the back can be removed allowing just the bezel to come out. Any input would be appreciated. I did manage to get the windshield wiper knob of and the nut removed so the only thing stopping me now is the headlight knob. Thanks, Don
