I can't understand why so many bikers spend so much for their bikes just to take big chances of being run down on the roads by not spending a small amount to put bright day and night lights on their bikes. I run two super bright Cygolite taillights during day rides, as well as slow flashing front light and a Brightside amber light on the frame for intersections. They can be seen a block away no problem. For night rides I put them on a softer setting. With so many distracted drivers on the road, we have alot of people getting hit by cars, even riding in the bike lanes. I see too many bikes going along that are hard to see. Makes no sense. I know the roadies worry about an extra 6oz. slowing them down but ebikers don't have that problem. As a retired trucker who has seen too many avoidable accidents, I say light em up and stay alive.
