We have an 04 Beneteau 331,a few days before we left NJ on our trip to the Florida Keys and Bahamas I tested our anchor light.It came on,all was well.The first time I went to use it in St. Michals,of course it did not work. I carry a back up that you can raise up to the spreader which worked well,it satisfied the fun police in Boot Key Harbor in the Keys.They were going around at night,boarding boats and giving tickets out to cruisers even if they had those solar garden type lights onboard. I replaced the whole fixture with a LED,which draws very little current.You may want to look in to a LED before you head up the mast.The owners package that came with our boat has replacement bulbs in it.
