to complement my other DRL on this post L.E.D Daytime running lights..... , and WOW what a bright little light. You can read more detail about them here BikeVis LED Lights - webBikeWorld. I also installed there modulator BikeVis PodMod LED Light Modulator - webBikeWorld too. What I like about this set up along with it's simplicity to install, is that the modulator really makes the light twinkle like a distance star or Christmas tensile. Just enough to get your attention. I made a simple bracket from a strip of metal I got at Lowe's for $1.19, cut it down and installed them behind the windscreen and panel. These light are bright but diffuse nicely so they don't blind drivers but the do see them. These pictures don't come no way close to there effectiveness but I hope you get the point.
