I'm not a proponent of red/green/white lights on kayaks, but you might like to consider the LED system shown in the link below.

: I'm a slow learner I guess and have a total of FIVE lights for my kayak, none
: of which currently work. That represents way too much money and
: frustration. I only paddle fresh water. I like to run a red/green front
: light and a 360 degree white light. Does anyone have recommendations for a
: durable marine light? I've even considered hard wiring in regular marine
: lights and rigging a rechargable battery pack to run them. Anyone done
: this?
: To date I have 3 Seatle Sports, the orange one that rotates on it's base for
: a variety of lighting configurations such as flashing, red/green, constant
: on. A nice idea but the switch is complicated enough that perhaps
: dependability is precluded....mine certainly haven't held up well. I have
: a couple of Innovative Lighting units that are simpler in design, but even
: they have not lasted like they should. Am I jinxed? or have I just not yet
: found that one reliable light on the market?
