[Diy_efi] The so called "Noid" lights ?

[Mike]

Over here in Oz, a "Noid" light seems to be just a simple LED
which goes in parallel with the injector, its a tool to verify the ECU
is driving its injector output and that the signal is getting as far
as the injector, ie All the way through the loom.

You basically, unplug the injector connector and plug in the Noid
light intot he injector and the injector connector into the noid so
the noid is "inline" to the injector, when the injector is driven the
light is supposed to come on.

My question is, 

Is this just a basic light or are there any inline type testers like this that
are any more sophisticated ?

I'm not complicating this at present with any Duty cycle issues, just wishing
to find out if people are using anything more sophisticated than a simple
LED for their inline injector testing ?

Regards

Mike
