This is a response to Colin who is looking for a particular replacement lamp. Try West Marine. I saw some like the one he describes. Also, I am looking for the number of a lamp for the anchor light for a 1981 30-foot Hunter. I don't want to go up the mast twice if I can help it. I asked Hunter but they do not have records that far back. FYI, you can E-mail Hunter technical service at huntermarine@att.net. Tnx.
