How do i trigger a light for shifting? Automatic

[logan binns]

ive looked but cant find anything. Has anyone done this for an auto. A way to have a small light (work as a shift light) trigger at a certain rpm. I dont know if will help but i have tuner pro rt and enhanced bins on the nvram which i should get soon. Thanks for your help guys

could just use a rev switch on tacho signal its just a box that closes circuit when a desired frequency is reached http://bolec.com.au/product/ss301-speedrev-switch-1224vdc-multi-range-2/

Hey thanks that's an idea I was trying to think if I could use a voltage signal off the tach and opens idk a relay to light it up. I'll look into it? Any other ideas?

Yeah it's not exactly cheap
From the little bit of research I did on it myself, it seems to be very simple when it comes to installation and shift light setup is a piece of piss

really need to use frequency for the switching as if u use voltage u can load it up and stop the tacho, and they are only a square wave also so voltage wont vary with rpm only hertz will
