Accon may not be a name that is familiar to a lot of readers but even if you have never heard of them my guess is that you will have either been on a boat with some of their products fitted or at the very least seen them at one of the boat shows.
Black Fin and Regulator sport fishing boats both feature the smart Accon pop up cleats which keep the deck clear and avoid damaged toes and feet. But now Accon have come up with pop up lights, which like the cleats sit flush with the surrounding deck when not in use but flip up at night when you require navigation lights. LED powered the 210 model shown at the bottom is a 2 mile visible nav light that complies with current USCG regulations.
I like the look of these lights a lot and I expect that they will find favor with a lot of the fishing guys who generally go out only during the day but have to have nav lights in case they head out in the early hours or get back late. The 210 model is available direct from Accon and has a list price of $177, expensive by some standards perhaps but it's hard to put a price on style.
