MSD Ignition 8991 - MSD Self-Powered Timing Light

A must for every performance tuner...
An accurate timing light is extremely important to the performance of an engine. This timing light does not require 12 volts, which means fewer wires hanging over the engine compartment for quick and easy checks. The light's power source is six AAA batteries. Its lightweight assembly is injection-molded for great durability, and it produces an intense strobe that is easy to view through 5000 RPM. For easy storage, a detachable inductive pickup cable is included.
