Wiring an aftermarket Lucas tail light

[Nortoon_imp]

I found out the hard way about British electrics on my 500 Triumph. The spark plug coils were under the tank mounted with cheap alloy brackets. One of the brackets broke and the coil touched the tank. That threw the timing off and seized the pistons. I was 370 miles from home in Laconia, NH at the time. That Turnip was the only motorcycle I ever owned that left me stranded.

I owned two BSA Lightnings and they never gave me a problem.
