My daily ride starts in the dark and includes crossing through many 4 way intersections. With just a headlight, cars from the sides were not seeing me and would often lurch at me, even when it was my turn to go. I mount these lights on the sides of my drop bars, out of the way of my hands, facing slightly forward. The flashing is bright enough that it seems to give me the visibility I was missing. No issues with them lasting 2-3 hours on flash, even in sub-zero temps.
Bought these for a fat tire e-bike that gets on/off road use day and night. Very bright and noticeable flash modes, 1st time used at night in a park a guy said he thought a car was approaching! I glued velcro on back of lights and put velcro on fork, just in case strap pops off or breaks. Works great. Bought second set of lights for road bike(s).
Amber bike lights seem to be rare, yet for riding with cars on pavement in daytime, i.e. to be seen rather than to see (at night). These (2 in set) are intended as side lights, but I repurposed each as a forward facing flashing light. They are bright enough to be seen from a distance, & IMO they help prevent the most common motorist-caused crashes with bicycles: pulling out in front of, and left-turning across. I also run a daytime flashing red taillight.
4 stars because they only last 2-3 hrs flashing, on one charge.
So far these have worked great. My commute is app. 45 minutes and I have been charging them app. once a week since the days have gotten shorter. Would estimate about 3 hours total running time on flashing mode. They are bright and I have not had any cars pull out in front of me on side streets since using them. Little concerned about the longevity of the elastic bands used to secure them to my bike frame. That's about the only thing that I would consider redesigning with these. They have addressed a longtime concern of mine to be visible from the side while riding at night.
Just enough distracted drivers out there for your entire lifetime.TWICE since I've used Beacon Light careless drivers overran the Stop sign by 20-30 feet, stopping before I was injured. Basically essential.
Using these on a fat tire e-bike. Side blinking lights really help bike be more visible at night when crossing intersections and while riding with traffic. I rode through a park one night, a guy there said he thought I was driving a car!
Great for being seen. Needs to be charged before every night ride because It loses battery life when not being used. I found roughly 2-4 hours of life on strobe compared to 6 hour claim. My other Blackburn products have significantly longer battery life than advertised.
I ride with these every day. I do not do night riding. These lights work well and last for at least 4 hours. They really increase visibility. For those who ride on streets and bike lanes anything that increases visibility is good. When you ride in shadows or on cloudy days they really increase visibility. I am sure they would be essential if you ride after dark.
