fourtrak ind. '94 hazard switch, headlight indication bulb in dash

Forum: 

Anyone got some advice for me. My hazard switch is not lit up when I put the lights on, I guess the bulb inside has 'gone'.Do I have to relace the switch,which works the hazards fine, or is it possible to get at the bulb inside. Also, my headlight bulb indication light on the dash only works on full beam, it does not indicate that you have put the side or headlight lights on. Is this normal?
Ta for any help.
