These spark plug testers work great easy to use and if your spark plug works a light appears to show it's working and if it don't work the light won't turn on so easy to let you know if your spark plugs work

These are nothing fancy or special, they clip good, light is difficult to see in the light which is the case with a lot of these test lights. When its too bright to use the light I simple stick my tongue on the plug n give er a crank and ya find out real quick! lol They do work and you receive 4 which is handy for watching multiple cylinders fire together. Overall a good deal.
