In order to build the head light at the handle bar, more than 12mm hole shall be necessary, and if the hole of these sizes is carved into the handle bar, the strength or durability of handle bar can be deteriorated. To solve such problems, we have made unique LED Hole shape in Can opener (Can tab) shape. This hole prevents the stress applied surroundings of hole to be concentrated on a certain point, so that it eventually prevents the damages on handle bar upon the process of hole. With this technology, we could make 25.4mm handle bar in diameter with possible ISO-City to be passed up to 560mm and 31.8mm handle bar in diameter with possible ISO-Mountain to be passed up to 700mm.
