So, I've had my 2017 Volt Premier for about 3 weeks now and wanted to give an initial evaluation of the ambient lighting package.
First, be aware that it is installed at your dealership, not at the factory. In my case, since no one had ordered it before, they didn't get the wiring installed correctly when they delivered the car to me, so I needed to have their service department figure it out subsequently and get it corrected.
Second, if I had it to do over again, I'd probably skip it, considering that I could spend $575 on more valuable stuff than this. Only four LEDs are involved in this system: one each under the left and right sides of the dashboard, and one in each front cupholder. That's it.
Third, it's not very bright, even at its brightest. In daylight, it's pretty washed out.
Yes, the blue color (among the several choices you can cycle through) nicely matches the blue shifter knob
So, my final impression is: meh.
