Jack and farmer,,,,,go superbrightleds.com, click on boat rv and other lite, click on boat rv replacement bulbs,,click on miniature wedge base bulbs, look at items 7,8,10 etc. I bought only bulbs to replace the 12 volt incandesant not the entire light fixture. I think I bought non polarized bulbs so I would match the socket looking up or down. Take one of your current incandesents get the bulb style number and I seem to remember a conversion chart somewhere in the bulb data base to verify your new bulb. About 12 to 15 dollars per bulb is what they are showing
