Check out the Hyper Whites from Hyper Lights. I have mine aimed in a cross pattern to get attention from either side, LED so they draw less juice, switch to modulate, constant on, or off. Small, easily mounted, and effective. Great to use if setting up camp in the evening. I fudge a bit and keep them on in the evening, figure my lights are still on constant, all I have done is add conspicuity. Over 2 years, passed many Staters, day and night, followed LEO, 2 and 4 wheeled, and never had an issue. Fixing to get a set for my KLR.
