I got my hands on the entire assembly of hood mounted BO light and the light does work. I'm assuming there is a 24V bulb in there. Is there a 12V replacement or is this a sealed unit? I have it broken down as far as seems to go and don't want to go prying things apart that aren't meant to be. Obviously I have no real practical use for the light, but would like it to be functional with a 12V bulb if possible. Any insight would be greatly appreciated.
