Why would you not recommend connecting it to a car engine sensor? The sensors I'm trying to hook up is the Mass Air Flow and Throttle Body sensors.
most sensors won't be able to do their job, the jt will cause interferences and they will stop to work.

cmos logic gates in the high state are often only disipating 1 ma

you could use 12 volts switch and 12 volts light to do the same.
but use your own pressure sensor switches and throttle switch, no matter if you are gona use a jt or not.

Has anyone ever tried this circuit? Does it work better?

Does 22n mean 22uF?

Hi All,
I must have had a bad connection yesterday. I will read today's posts in a moment,  but first, I want to say The second tier bjt led is not necessary for the second tier "secondary" leds to stay on. (I had stated that it was)

I may need to re-draw the circuit. I am not sure that second tier secondary correct. It only has 1 wire from the secondary on one side of it
The other secondary wire is straight in the neg rail.
