| This listing is for a single noid light. For those of you that don't know, a noid light is used to plug into an injector connector to show if there is a complete and operating circuit going to an individual injector. This is a must have, if your injected z doesn't start or if you have a cylinder that isn't firing. If you have a good operating circuit going to an injector, then this noid light will flash a pulse indicating a good circuit. A regular test light won't work because the voltage is too low on this kind of circuit, and a VOM won't work because the electrical pulse is too short. A noid light is the only way to go. These are temporarily a special order only item. Please allow an extra week for delivery. We can ship these anywhere in the US via the postal service for 6.50 in a padded envelope.
