I'd have just used the cheap-o all-round white LED anchor light on a short base from WM, but the bottom is solid black, and I wanted the light to be seen from closer in, especially since it's up on top of the mast. Down low, the visibility would be solid at any proximity, but with it up high, it would dim to black at relatively far away. Plus I had the base, socket, and lens that wasn't really doing anything anyway, and needed a job.
I cut the knob off one of my older son's broken baseball bats (I have a mountain of them) and turned a spigot to go into the pole I stole the bulb socket from, as it's just a flag staff anyway (socket in the boat coaming also holds the long all-round white pole light I use when motoring without the mast, with the stern light turned off).
I left his number on it (college team).
