I have a 2009 Piaggio Fly 150. I am trying to convert to LEDs. The bulbs in the front, parking and signals will accept a standard 1156 based bulb. The rear is different. The signal bulb is a single filament with a strange base. Instead of the two indexing pins on the side being located midlife they are offset to one side. 1156 bulb will not physically fit in the socket. Tail/brake bulb is the same way. Makes no sense that the front lights are industry standard, yet the rear is like it was made on a different planet.
Any suggestions or ideas how to correct this, or anyone know of a source for LED bulbs?
