I picked up a handy LED red/green and white light and strobe combo light in Newton,MA at a Charles River kayak center. I keep it attached to my life jacket by the helm station for emergency lighting. I just took a look on the web and found the device I have available online. I have had it over a year and its still going strong for something in storage all winter.
