Now in the dark winter months, this was the best INVESTMENT, we have made. Motorists see us now from afar and take a wide berth. The lights are very bright and really worth the money !!! The lights we have not mounted using the supplied clamps or Velcro to our Hartan KiWa but with simple cable suspenders and the holds bombproof. The clamps, you can apply only to round bars and the Kettband has unfortunately not kept quite as tight. That is why a star deduction. Still, I can recommend the buggy Lights only one mom who goes for a walk with her stroller sometimes even in twilight. There is a good and above all peace of mind to be equally visible from all directions.
