Tems control button lights, defrost switch light, fog light switch light, cruise control switch light. Then you can change all the regular automotive bulbs to colored led style also. Also, if you do a little work you can also change out the drivers side exterior door lock bezel light if you can find a 5mm recangular LED in the color you want.
The Tems light indicators are something to talk to maybe CRE about. I had them apart and they aren't a standard LED, don't know what to call it but it looks as though you would have to make a board to install new LEDS onto.
