Cruise Control decals on steering wheel

I have a 2005 Chevrolet Impala that has the cruise control buttons on the steering wheel. The decals are coming off, in fact one of the is just a green light that blinds me whenever I turn the wheel:sunglasse. Is there anyplace to get new decals, stickers, whatever you want to call them, or do I have to replace the cruise buttons entirely?? And can I get the buttons as a stand alone, instead of purchasing an entire system? And finally, how difficult is a task like this? Thanks in advance to everyone for any help/tips.
