replacement dock light bulb

One of my bulbs blew on my 2012 Sweetwater 2086 and I need to replace it but can't seem to find what the original wattage and voltage is, so I don't know what to look for. How do I identify the wattage/voltage for a replacement bulb and whether it's halogen or xenon?

Just bought a 2013 Sweetwater 220SL3 and the left (red) Nav light is not working. I unscrewed the fixture from the panel and no wires were hooked to it, how do I remove from couch to get to the wires. They must have fallen down. Thanks!
