Custom Shift Light (??)

[91MitsEclipseNT]

does anyone make a tach control were i can still use my factor tach and use LEDs to make a shift light. i dont want a big ass monster tach with a light and thats all i can find. i need something that will just tap into my signal from my ign. and power my LEDs at a set RPM.

i work at advance auto, so anything auto meter sells i get 20% off, and i can't find any such control in the catalog.

maby you can take off all the plastic and use just the led

There is a way to make a custom shift light. It's basically a voltage activated rpm switch. I've got the instructions printed out at home, but unfortunately for you, I'm at school. If I remember, the parts only cost around $30, and you set the rpm's by turning a knob. If you know at least a little about soldering and electronics you should be able to build the circuit. I'll keep searching for it and if I come across it I'll post here.

This chip can easily be used as a shift light, and its $1.80 at www.digi-key.com Download the datasheet, it has a ton of reference designs/typical applications, one of which is exactly what you are looking for.BTW total parts cost will be less than $10.
