As early joggers I want to see potholes (Thanks Angie and Co) early, just as one should recognize me. This lamp is very comfortable to wear. The big advantage of the lamp is that the battery compartment and the lamp in a compact housing are very good. The lamp can emit white light flashing or permanently but also the red light also flashes or permanently. Of course, the light angles can be individually and precisely adjusted. Here you can tell the quality clearly. I am very satisfied and can only recommend to buy, more money is here more power.
