Well i had a masthead light which was sealed with rubber grommets, the top
was plastic and screwed from the base upwards with a long stainless screw,
therefore holding it down from the inside. About a year after fitting the
bulb blew so after climbing the mast i found to my surprise that there was
about an inch of water inside. So bearing in mind what has been said here
How did that water get there?

Wind-driven rain, most likely, and they forgot to put a drain hole in.
