Carello PF 130 (Italy). 6 volt halogen lamp.
To operate it, I used a single speed wiper pull switch located in the old choke opening.
It's fused to the low beams so it can't be left on or used without them being on.
This is the driver cover. The minty one is put away, but this one polished up nice with some tire black.
The white license plate is history.
