This headlamp was a complete disappointment for me. According to my experience, it's not suitable for automotive purposes at all. The light is not strong enough to give a clear view of the engine parts and it doesn't last very long. Although the belt extension cable is a good idea, it's not worth it if the light isn't bright enough to use.The only pro is that IT`S easy to wear. The cons are numerous including the light being too weak and not suitable for automotive purposes..
