The lamp is pretty small and has a rear clip so that you can attach them also to clothing (eg if you go running). There are 2 rubber rings for fastening with this. You need to attach a screwdriver to the holder. The lamp is simply clicked and by a small lever (below) dissolved again and pulled upwards. The power button is on the bottom of the lamp (narrow body). Function: continuous light - flash - off.
It is operated with 2 x AAA batteries. There is to open on the side a small slit where best to reinsteckt a screwdriver and then aufhebelt. Goes very quickly and then it is simply clicked together again.
Conclusion:
A very well-processing lamp at a low price. Ideal as a permanent light or running or the walking the dog (but then flashing, attachment to clothing or linen, I do it the lamp behind the running cap :-)
to the video:
The video I had to shoot so I think it has become not so good alone. But I think you can see the features of the lamps. In the review of the "CATEYE battery lamp Rear TL-LD 610 R, red" I still have a video set where at times you can see the distance lights.
