Good morning, gentlemen,
I have recently acquired an all original 1974 ts150, and I would like to upgrade the electrical to 12 volts with a powerdynamo system as I did with my 250. I know I can get a 12v flasher unit, headlamp, brake and indicator bulbs, but the troublesome ones to locate are the tiny bulbs in the speedo and turn lamps in the headlight bucket. Does anyone out there know of a good source for these, or an alternative bulb I can source easily in the US? Or would it simply be easier to get a 6 volt powerdynamo (which I believe they offer)? The fellow at my local hardware store literally became angry with frustration when I brought him a bulb he could not locate for me. I give him credit, though, he had everything except the headlamp and idle light bulbs.
