Use to check the power to the plug
Arrived on time, suitably packaged. Used to test the spark on a petrol engine; a Clark power washer with Honda G200, it should fit any standard spark plug. 2nd one in 50 yrs! I could not find the old one, which was a bit different so bought this one. Cable is a bit short but was ok. The exposed plug part is a bit long but again ok. Did the job. The clear plastic lights up if the connection is good. This tells you if the power is getting to the plug.

Great little gadget
After several reviews complaining about failed bulbs, I ordered this with some trepidation. I needn't have worried. The device is extremely simple: you plug it in between the existing HT lead and existing plug, and it flashes neon-red every time the plug sparks. I was concerned that the gadget wouldn't fit the plug in my mower: it fitted just fine. (In fact, I didn't find a plug it didn't fit - even motorcycle plugs were OK. It seems pretty universal.) Perhaps the only drawback is the male contact (the stick bit, that fits the existing HT lead) is quite long - great for when you've got shrouded leads, but a bit awkward when you haven't (because you have to make sure it comes nowhere near any earthed metal. I'm going to try wrapping a piece of heat-shrink onto it. I found the flash to be clear and perfectly bright enough for my workshop, (note to reviewers who said the bulb was dead on delivery: it's a neon - it's not supposed to to test continuous!) and it saved me hours tracking down a fault in a magneto circuit. Overall, great little product, great price, seems very reliable (nothing really to go wrong). I can see it will be part of my toolbox for years to come.

A must have tool.
Bought this as a means to test my ignition system on my brother's car. Too make sure that the ignition system works.

Good for testing circuit

No good for coil packs
Metal shaft is too long for testing coil packs. Spark just jumps from tester to outer body of coil pack.
