Review on Discontinued Genuine HeroBeam® Bike Lights Double Set - Get It Now! by Saradhi Suter

Based on other reviews, I mounted my lights under the handlebar, took some rides, and they stayed in place fine. The front light is able to slip out after loosening a well-placed knurled knob, but the mount is also easily removed by loosening another well-placed knurled knob. Since the mount looks like it would hold nearly all the popular small LED flashlights at nearly every checkout stand in Hardware or Big Box stores, keeping your mount may be the biggest issue. If I were to leave the bikes in a public place for long, I'll probably remove the mount and light. I use it in daytime for the strobe, riding through shady neighborhood roads where front reflector is ineffective during the day. On a recent ride, I could see my wife's strobe in shade and bright sun. I'd replace the mount knob with a screw, but if I were to ride at night, I might want to reposition the mount for the conditions.
