I'm going to quickly hijack this thread. I need to replace one of the vent wheel bulbs in my car, but I was wondering if it was possible to update the interior lighting.
I know the dash and vent wheels are all 2721's, but they give off a yellow-white glow, and the window switches by the shift lever are all yellow LED's. Compared to the blue lights from the console of the new Honda Fit that's in the driveway, it looks quite dated.
So, I was wondering about updating the interior lighting to blue-white LED's and bulbs. There's supposedly drop in replacements for the 2721's here:

Has anyone tried them, and are there any adverse effects to the electrical system? How about replacing the yellow LED's in the window and other console switches, has anyone tried that?
