shift light indicator?

[gaf99]

will they work on the "tach-less hatch" without having to buy an after market tach as well? I mean can you use just the light?

Probably, but how will you calibrate it without knowing the RPM of the engine?

not sure. i was looking at this web site http://www.raptorperformance.com/
some have the dial settings on the side of the LED. don't know much about cars but i thought this might work rather than installing the tach?

Ι think it will work, but it is a bit difficult.
