Yeah, don't think I would ever try them, I get freaked out the darker it gets.
You should definitely try some night surfing sometime. Summertime, full moon sessions are great. Whole different world. First time you do it, head out with some buds so you don’t get too freaked out. Your mind will start to play tricks on you. No doubt. Just remember, it’s no different than surfing during the day, just darker. Makes judging your take off a little more difficult.
People used to wear glow sticks so that they could be seen from the beach. You'd get all these neon green and pink and blue streamers burned onto your retina. This is kind of the same idea.
