For quick, easy tuning, use self-powered timing lights from Powerhouse Products. Suitable for 2- or 4-cycle applications, they feature the desirable one-wire inductive lead design. Since the tool operates on two "D" cell batteries (not included), there's no need to connect to the vehicle's battery—that means fewer wires hanging over the engine bay area! Magneto compatible, the lights incorporate a bright xenon flash tube for use in sunny daylight conditions. Get ready to tune like a pro with Powerhouse Products self-powered timing lights!
