i didnt buy mine from that exact person, i sent mine to a old guy in toronto who did exactly the same thing, it was around the same price too! ive never had mine on a running engine so i dont know how it works, but he did say that its a small armature and that it dont put out many amps but its 12v safe and it looks like the old deal if your after the old looks and brighter lights id say go for it!
