That lighthouse is the focal point of my 3rd jersey for the Islanders. It is a simplistic look, much like the Lightning have done when the rebranded; I've taken an "icon" from the team's history/the essence of what the team is all about and made a very simple, yet aesthetically pleasing look for them.
From there I took the jerseys the Islanders currently wear and put all of the lines and stripes on a slant to continue with the consistency of the jersey and the logo. Finally, I've given the Islanders their retro blue back because it is a good look, although I think the Navy is a more solid primary look for them.
