RE: steaming light
Hello Bud,I don't know the part number but the bulb is a pretty common one found in automotive uses. It has the base that pushes in and turns and has two little pins on the side that hold it in the socket. I was having trouble with mine before I launched and had to troubleshoot the whole thing. I found that the bulb wasn't my problem but the plug had just enough corrosion to not make contact. Use some vaseline or WD-40 on the plug and in the socket and you should be good to go.Should be able to find the bulb at an auto parts store or West Marine. I will look and see if I have a spare for the number so you can get it before you get the mast down.Jim
