Laser 2780 Ht Lead Ignition Spark Tester, Red

Had an intermittent fault on my 1963 Triumph motorcycle. Tried diagnosing it on the road side by removing spark plugs and checking for a spark but this was inconclusive and a pain to do. These simple testers did the job really well. Fitted 2 (it's a twin motorcycle) and rode around for a while until the fault occurred. I could clearly see that I was loosing the spark to the spark plugs. Not sure when I will use them again but a useful addition to the toolbox.

handy as tester as per intended use. Good indication when on car. Good diagnostic tool to view spark with engine running and saves taking plug out on initial testing / fault diagnosis. Easy to see spark inside and very bright. Reasonable money for what they are. Now and again intended use.

Product is great and what i wanted. However, the package was left on top of our gate and not handed to someone as stated by the delivery company. Not an issue unless it's either raining or a passerby takes a fancy to an interesting looking box sitting there within easy reach.

Did exactly what’s was needed. Also had the advantage of showing my kids what spark plugs do :)

this tool helped and saved me money.. I changed one of my coils due to no flashing light .. i had a spare coil ..now works great ..thanks

Cheap spark plug tester works well good price.

Works well very reassuring.

Saved me getting shocked! Never seen these before, so bought a set and they work as expected. Saves pulling plugs and earthing them out. Recommended and seem good value to me.

Schönes Produkt. Funktioniert sehr gut mit den herkömmlichen Zündkerzen z.B. Twingo 1 Bj 2003 (Zündkerze NKD). Wenn man alle 4 montiert und mit Slomofunktion des Handys ein Video aufnimmt, kann man z.B. feststellen, ob die Zündreihenfolge korrekt ist oder eben nicht. Den Funkentest (Zündkabel bei laufendem Motor abziehen) habe ich natürlich auch gemacht. Hier kriegt man allerdings nur die Info: Funke Ja/nein. Das Bauteil würde ich der Kategorie "Spielerei", oder eben geeignet für genaueren Analysen zuordnen. Wie es im Betrieb aussieht siehe Foto.

Doet wat het moet doen. Duidelijke vonken te zien bij het testen. Eenvoudige manier van testen!

Tempi consegna eccellenti Che dire di loro semplicemente comodo utili Vediamo robustezza materiale nel tempoSe avesseroesso gli adattatori per le candele con filetto sarebbe stato il top

Work perfectly.
