OK ... was expecting more.

The light actually looks as if the red field mitleuchtet. But this is not so, the red box is nothing more than a reflex reflector. The light comes from two red LED dots that are located behind the light "glass". Viewed from the side, the signal effect is not good.

Battery replacement is easy to do about solving a screw. The build quality is impeccable and the price is cheap. Two AA batteries are in the supply.

In my view, the only advantage of this but very large lamp that you can unscrew the lamp to a porter and the cheap price.
