Yes I now have these available to buy,
From my thread on how I made mine,
http://www.zpost.com/forums/showthread.php?t=160920
I have had a lot of interest and request to make one for other people,
I have listened to those requests and have made a few for sale,
These can be fitted to non M cars too via 2 wire hookup,
These are made from brand new ZHP knobs, custom made with my own electronics and give off a very stock OEM look,
They look much better in person, They are very hard to capture with a camera but I did my best,
I am selling these for $150 per knob,
I also have the ability to make them in custom colors and am actually making one right now in a custom color for a board member,
Custom colors will cost a little extra due to buying other leds/components,
I can also convert your existing ZHP knob to lighted if you wish and the conversion cost is $100 per knob for stock color, again custom colors would be a little extra,
I'm only going to be making a few of these knobs as to be honest they are a bit of a pain to make, They are VERY time consuming and not much joy to make,
You have to think these have been around for years, If it were easy and profitable to make these ZHP knobs lighted I'm sure someone would have done it by now,
Truth is its not easy but I just couldn't believe the amount of emails and PM's I got after I made my own,
