Automotive Spark Indicator
This Tool can test spark plugs, spark plug wires, and coils without puncturing the wire.
With the engine running, place the grooved end of the tool over the spark plug wire.
The bulb will flash to indicate spark.

 

Features:

Blunt nose tip prevents lead puncturing

High intensity bulb and viewing window for greater flash concentration
