Found this on legacygt.com... Very interested!
It's on the Mrs' Cruze from factory, also most newer Euro cars. When I first drove her car I was pretty keen on the idea. Tap the indicator stalk (up or down) without clicking it on and it signals 3 times and then auto shuts off. Perfect for lane changes on the highway, within reason, and around the suburbs with minimal traffic, etc.
This guy sells a replacement module which goes where the original Denso indicator/hazard module was from factory. Retains all normal operations just adding the touch-on function. Also does a "wig wag" or something, looks like an emergency car's lights when sirens are on. Useless but another feature anyway.
Also you can change how many times the indicator flashes, 3, 4, 5, etc..
They are going for about $79 USD but he's given out all instructions to make them from a couple of dollars worth of parts. Unfortunately electronics, soldering, and his schematics are all beyond my ability, however I'd happily give it a shot!
Thought some of you guys might be interested.

His site http://www.autowindow.com/orderTAP.html
If anyone wants to clarify (dumb-down!) the instructions for me I'd be stoked! Also no idea where to get the parts... Perhaps Jaycar? The heart of this mod is a chip which by way of a Google, looks like Jaycar stocked years ago, but not any more.
Let me know what you think. I'm aware of a select few who flame the idea over on legacygt.com. But each to their own. I love it haha.
