Proform Self-Powered Timing Light
Simplify Ignition Timing Adjustment
This budget-friendly timing tool minimizes the challenge of setting a vehicle's ignition timing. Its lightweight design features a protective bezel and built-in flashlight with spare bulb. Plus, there's no need to bother with battery leads. The unit is powered by two "D" batteries (included) and hooks up with a single wire: just connect the slide trigger, open, place over the #1 wire, close & it's ready!
