Kyrgyzstan issued in 2018 two stamps and a miniature sheet which shows us lighthouses around Lake Issyk-Kul with shipping on the lake.

100 kgs shows a lighthouse and on the lake a tug with a barge in tow, on the tug and barge I have not any info.

150 kgs shows the passenger ship MOSCOW viewtopic.php?f=2&t=15607&p=18040&hilit=moscow#p18040 and leading lights. https://en.wikipedia.org/wiki/Leading_lights

The MS shows us in the border a map of the lake with all the lighthouses around the lake.
