I bought some self adhesive waterproof leds in 5m strips off ebay for my centre console, they have been faultless in what I would call a very wet boat for the last 4 years. Unfortunately I cant come up with anywhere to put them in my Zodiac without them dazzling me.
I also have underwater leds which are great for attracting fish at night and finding the boat while night diving.
Cost $7 per 5m strip (3.50 quid) ebay
