Our pick
Innova 5568 Pro-Timing Light
Choose the Innova 5568 Pro-Timing Light for 12V negative-ground timing checks. Check your vehicle’s ignition arrangement against the light’s compatibility list before use.1
Why this one
- Its inductive pickup clamps around the No. 1 spark-plug lead; check that the 6 foot leads reach the pickup point and required power terminals.1
- The tachometer and 0 to 90 degree advance scale provide separate engine-speed and spark-advance readings with one tool.1
- Detachable leads and the included storage case keep the light and cables together between jobs.1
