I will have to give the overall topic some careful thought before offering any input. In the interim, however, for BOB M. and LIGHTHOUSE DUO and their model train interests....

Are you familiar with the lighthouse structures available from KIBRI for HO and N gauge layouts? [Yes, Bob, I know that Lionel is O-gauge, but train enthusiasts look at everything!]
KIBRI has three that I know of:

Item 7300 [N scale]: http://www.reynaulds.com/Kibri/temp.asp?item=7300

Item 9152 [HO scale]:
http://www.reynaulds.com/kibri/temp.asp?item=9152

Item 9153 [HO scale]:
http://www.reynaulds.com/kibri/temp.asp?item=9153

Or have you been gluing your Harbour Lights to your layouts?
