The classic material for port light gaskets is felt. When I replaced my almost 30 year old rubber gaskets in my bronze port lights six years ago, I searched around for what I thought would work best and settled on some appropriately sized weather stripping, and I used marine silicone to caulk them in place. This was a terrible solution, and gave me trouble from the beginning.
Then last year I found out about felt. Ordered square felt in the right size, used a little bit of contact cement in the groove to hold them in place a little better (they fit well). Got the felt from a company I found on line who specializes in it, and they cut it for me. Was a bit expensive, and the minimum order was a lot more than I needed (not your size).
Was very easy to install after cleaning the grooves in the port lights. Cut one end on a bevel, and put it in the groove at the top, then lay the felt in the groove until it meets the other end, then bevel it to match the other bevel. Cut it a little long rather than short, since it compresses in length, and will fit in the groove nice and snug against the other end.
Works great. I'll try to find the name of the company I ordered from in my email queue and let you know.
