regulator / rectifier for Aprilia Atlantic, Piaggio Beverly, MP3, Vespa GTS / GTV IP40366

Rectifier / regulator changes the AC into DC on a 12V board. This prevents bulbs from burning through. Exposure to high temperatures means bulbs often fail. If the rectifier is faulty, the ignition system can falter, the bulbs burn through, and the headlight flickers.
