John,

First, congrats on your reaching wacko-dom.

HL did put out a map of the US with their lights listed several years ago. It has been out of circulation for a while, and would not be anywhere near current with all the new additions each year. Coming at this from the other direction, you could acquire a map of US lighthouses and hightlight the ones HL makes. Such a map is available, but I am not sure if it shows all the lights in the US or just the "popular" and better known ones.
