Spark Indicator Ignition Tester Spark Plug Coil & HT Leads

This spark indicator ignition tester is used to check whether ignition current is reaching the spark plug, coil or HT lead. It gives a simple visual reading through a flashing bulb, making it easier to confirm spark presence during testing. The non-puncture format means you can carry out checks without piercing or marking the wire, which is useful when diagnosing faults without causing unnecessary damage to ignition components.

It is useful for fault-finding during vehicle servicing, maintenance and general garage work. When an engine is misfiring, refusing to start or running unevenly, this tester helps narrow down whether the issue may be linked to the ignition side of the system. It can be used by mechanics, mobile technicians and DIY users who want a quick check before moving on to more involved repairs or replacing parts unnecessarily.

For regular workshop use, the straightforward design helps keep testing simple. The clear flashing bulb is easy to notice while you work around the engine bay, and the pocket clip makes it easier to keep the tester close by between checks rather than leaving it loose in a toolbox or on a bench. The non-puncture design also makes it a sensible choice where repeated testing may be needed across several vehicles or during step-by-step diagnosis.
