This sounds like a great idea, but I don't think it can be done.
None of the bulbs I have tried worked, just so you know. Single LED bulbs tend to be too dim. I tried some triple led bulbs but they didn't work for long..in order to get to the climate controls you have to remove the dash panels around the headunit. then u remove the panel thats directly underneath it (pops right out). popping off the cover for the climate controls is very easy and straight forward, 4 small clips along the outside that you gotta pop it off of.
heres the inside of the climate control
