Simple installation, this kit comes with a cigarette adaptor and you just plug it into your car's 12V battery socket and it's ready to go!
It probably works, but I would not use it. I would only trust a shiftlight that get the rpm signal from a real rpm source, like the ignition.

I agree to where the source of the signal comes from, but if I were going into that I would probably be lookin' at up grading the ignition and the MSD. set-ups which allows for straight plug in of shift lights (some w/out module so they say), not to mention other programing capacities incl. timing, rev limiter etc. just my .02

I think JoBy's explanation is probably how it works but that's probably why the rpm range is adjustable. If it reads the same every time then I don't see why it wouldn't work. You would want to make several "runs" with it to verify that the light is coming on at the same time every time. I guess it would depend on the $$$ factor whether I would try this or use the proven ones.

It isn't necessarily the $$$ factor. I wanted a small shift light like a Harlan, but can't find one anywhere... and the tiny one MSD makes needs another 100 worth of accessories in order to work on the vette. I can score a Proform that is good quality and cheap too... but they are rather big and I don't want to drill holes all over my interior to mount it. I figured this would be a nice way to have a shift light that isn't a permenant fixture on the middle of the dash... I just didn't want to buy junk and wasn't sure on the operation of it.

Can you not get a Harlan now? I got mine 4 years ago and it took like 4 months to get it. I remember just writing it off because the guy wouldn't answer emails or anything. Then one day it just appeared in my mailbox 
Love mine, btw, and did the installation like Hutch on the GSR website:

Back in the old days(early 90's) the only shift light was an autometer. Big and bulky. I installed mine in the defroster duct. Steathy and bright. Has been working perfectly for 13 years. if space and bulkyness is an issue consider hiding it in the duct.
