One of our Fleet members gave me a couple LED lights.. They are like a glow stick except for they are battery powered.. he said they were cheap.. Like a couple bucks or less each cheap...
A little electrical tape to block part of each lights 360 view making for the 'proper' light pattern.. and a couple zip ties to secure the lights to the Bridle..
You can also just buy red and green glow sticks pretty cheap..
Not USCG approved.. but around here.. with one else generally on the lake I just can't see getting hassled to much. especially if a decent effort was made..
Last time out though I opted to go ninja.. I didn't want the other H16 to see me sneaking up on him.. So I just strapped a flashlight to my life vest.. Just in case...
A google search for battery powered Bow lights shows all kinds of stuff which could be secured to the chainplate..
Night sailing is so much fun!!!
