The lamp is the conversion from the side runners to scars Dynamo. The lamp is very easy to install and connect. The switch makes the whole lighting can be switched off. The holder is made of black plastic, but it makes a robust impression, and I so do not worry that it gives up quickly. Nevertheless, I continued to use the holder of the old headlight. How many LED lights is the light cone very bright, but also very distinguished and the headlight does not scatter as much as I'm used to it by the halogen lamps. However, the spotlight is a buy rating.
