T140v 1976 missing electrical system

No criticism intended. It's your money and your bike, spend the former how you want to make the latter look.

Fwiw, the M&P turn signals I've used; when I bought them, they were also available with dark and clear lenses (like these from the same supplier) and chromed and plain polished ally bodies.

Thouse are very nice! Found these LED much cheaper in case I decide to give it a try.

I need to give it some thought. Meanwhile these just arrived
Bought it from RGM Norton Ltd arrived in 24 hours and aprox 20 pounds cheaper than directly from Boyer Bransden.
