If only we could wire the things up to a generator !!
I'm working on wiring each valve cap to a very large capacitor, should really link this to a CCTV, it would be such a pity to miss the resulting antics........he he....... :winky: :winky:
By the way the spinning caps work well, after I lost my last locking ones with the Lexus emblem on I fitted them, OK so far.
