The goal is to have amber rear turn signals instead of red-on-red. My commitment to doing this small bit of customization was solidified by A) barely being able to see a black Volt signaling in front of me on a misty and rainy highway, and B) reading this material online: http://www.acarplace.com/cars/turn-signals/

 

Attached are photos of our 2014 white Volt, a 2013 'Holden' Volt in Australia with the (required anywhere outside of north America) amber rear turn signals, and 2 photos of the assemblies I had sent to me (not by Holden because they were disallowed by GM from shipping anywhere outside of AUS—thanks again, GM).

 

So I get the assemblies and they look great, complete with GM sticker. But CAUTIONARY NOTE from a forum comment remarks the following:

"Don't forget you'll need to bypass the integration module, the extra electronics that GM has to add in order to go with all-red tailights. That's right, people, the car costs MORE in order to have ****ty red turn signals than to just go with amber. Not to mention the logistics of making and shipping two different kinds, one for USA, and one for the rest of the world."

 

UPDATE, summer 2015:

After spending another couple of hundred dollars for an (electric-vehicle experienced) auto electrician for testing, it comes down to the Volt’s computer. Some of the pins on the assemblies are for data. So evidently, when one hits the turn signal lever, it’s not sending an electrical command to the assembly, it is instead sending the command to the on board computer.

Upon startup, the computer wants to ‘handshake’ with everything, and the AUS assemblies won’t handshake properly.

So I am now stuck again, unless and until I can find a Chevy dealership who can help me with the programming tweak it would take to integrate the amber-signal GM assemblies.  I’ve pondered the idea of telling a dealership that we plan to ship the car overseas—but would that once again give GM the excuse to cancel our warranty?
