Surely there is someone out there that has read this request but hasn't taken the time to check their inventory or lighthouses for their serial numbers. I'm just asking for HL365 thru HL399 and their serial numbers IF THEY ARE OVER 550. It will only take a minute and it will help me make the Revision 2 2013 Harbour Lights Product List more correct. If you don't want to list your serial numbers over 550 here on the Forums then send an email to flacoastie@embarqmail.com to give me the information.
