I went out again, to a pitch black garage. I can barely see them on her 09 SG due to the rest of the dash lights ambient light, but I did see it this time.
My SESG, which has the blue light conversion, the buttons don't light up at all. It's not an issue since they're readily visable from the ambient light of all the gauges. Had I known at the time, I probably would have had the buttons converted, also.
JCZ,
The way the LED circuit is set up is pretty tricky. If all the LEDs installed to change the backlight on the display were not done perfectly, they will actually take out the button backlight as well as make the display backlight look a little washed out.
