    An accurate timing light is essential to getting the most from an engine, and MSD's Self-Powered Timing Light is a tool every performance tuner should have. It doesn't require a 12-volt connection, so there are fewer wires hanging over the engine compartment for quick, easy checks. The light runs on six AAA batteries and features a lightweight, injection-molded assembly that produces an intense strobe visible even in daylight, with a detachable inductive pick-up for easy storage.
