How to make Head lamp from iron plate is easy, but need special skill that is welding. I made a minimalist Head lamp for electric bicycles. Although the result is not as good as manufacturer, but I am happy. This Head lamp fits in pairs on the motorcycle, although the shape is strange but I like it.
