bulbs
Bruce-The Anchor and steaming light are both single element 12 volt bulbs. Assuming that they are the original equipment fixtures that came on the boat. Were it I, to be safe, I would get a couple of potential bulb candidates and save the receipt. If you explain to the clerk at west marine or boat US then they'll let you return the unused bulbs which are obviously not burned out. Take along a #1, #2 phillips head screw driver as well as a common screw driver and a knife to clean the contacts.Lastly, a small plastic pail attached to the bosuns seat to put parts in when disassembling the whole shmozz.If you want to put your binoculars on the fixtures before you go up they should be round glass hemispheres. Good Luck,Mike
