An accurate timing light is extremely important to the performance of your engine. MSD's new Self-Powered Timing Light is a tool every performance tuner should have. A great feature of the Self-Powered Timing Light is that it does not require 12 volts. This means less wires are hanging over the engine compartment and makes for quick, easy checks. For power, the Light uses six AAA batteries. The lightweight assembly is injection molded for great durability and produces an intense strobe that is easy to view even in daylight. The inductive pick-up is detachable for easy storage.
