School me on stand alone shift lights. I was to cheap when I bought the tach to get one, but now I think I do. What is a decent one to get and what is involved with all the parts needed to make it work. I have an MSD box if that matters. Thanks Bill

MSD would be my choice.. The info you need is in the cat IIRC..

I have an MSD one myself. It just plugs into the tach port on the MSD box. You change the chip in it to change shift points.

Just a note: If you use a light and a tach, the shift light will flash a couple hundred RPM below what your chip says. That is so you have time to get the shift in before you go above your target RPM.

Many thanks to both of you for the advice.

I got one here:

Easy to install. One wire to ground, another to a switched power source, and the last one to negative side of the coil.

I also have one from Raptor...works very well
