Most I like the small, compact shape both lights. They can thus be discreetly at the wheel mounted and deliver an amazing amount of light. The LED technology provides the front light 16 LUX whole thing though for trips ranging on normal roads, but not bright enough in the forest. The same applies to the rear light. So if you really want to play it safe, you should still attach additional reflectors on the bicycle.
The lights can be quickly and easily mounted on the wheel without tools are required. Both lights can be permanently fixed using cable ties. The burn time is relatively long, thanks to the LEDs, so you do not have to constantly change the batteries in regular use. The front light even has an indicator that lights up when the batteries are drained. However, I did not have to change the batteries so far, so I can not tell if it performs its service.
Overall, this kit is practical, flexible and thanks to the compactness also be fitted easily on the wheel. However, anyone who is in the darkness, away from halfway lit roads and paths on the way, should eventually establish brighter lights or additional reflectors there.
