This is probably the best source:
NGA List of Lights
"The List of Lights, Radio Aids and Fog Signals is published in seven
volumes, as Publication numbers 110 through 116. Each volume contains
lights and other aids to navigation that are maintained by or under the
authority of foreign governments."

<http://msi.nga.mil/NGAPortal/MSI.portal?_nfpb=true&_st=&_pageLabel=msi_portal_page_62&pubCode=0007>
The US also have another lights list for US

<http://msi.nga.mil/NGAPortal/MSI.portal?_nfpb=true&_pageLabel=msi_portal_page_62&pubCode=0014>
For the US the NOAA have publicly accessible ENC marine charts which show
'lights':

The US also have sailing guides:
