You need to remove the instrument panel to access the switches - the actual bulbs inside the switches are tiny ones the size of a grain of wheat. You can get now ones from Jaycar or Dick Smiths or Holden agents I'd imagine. I pulled an old car radio apart and soldered the ones from the radio in. Don't forget to disconnect your battery before playing around as if you dont and maybe turn the ignition on you will end up with all sorts of fail codes. Do a search in the 'how to' section for the power/economy switch light and also the instrument panel as they've been covered before. Good Luck..
