Skene Photon Blasters. Stupid name and a great product. A small device about the size of your thumb that increases your visibility/conspicuity to others. When the light output from the device is presented to another driver's peripheral vision, it flashes or flickers. When one looks at it straight on it appears to be a steady light output. Very bright. Substantially reduces the amount of folks that even think about pulling out in front of you, in my experience. Best purchase I've ever made for a motorcycle.
I can recommend PIAA LED driving lights. They make a proper driving light pattern, they offer excellent illumination, and they draw little power. Only detractor for me is that the light is distinctly blue.
