Classic styled tail light for nearly anything you want to mount it on. We've seen these look really great on Puch Maxi for example. Some older Malaguti mopeds came with a nearly identical tail light as well.
Really though, you can put it on anything but may have to drill a hole for the mounts to line up.
Comes with a 6V21/5W dual-filament bulb!
Mounting bolts are vertical and 62mm apart.
