I know this is an old topic, but can someone please help me with the info I need to FIND/BUY replacement bulbs for my factory stereo and what the process in the swap in my 2001 Bonneville. Thank you in advance.

I don't think they are bulbs that you plug in....I think they are soldered to a circuit board....sometimes it'* just a soldered joint on the circuit board, because those LED'* last forever....if all the bulbs went out at once, I would be looking for a circuit board problem.....if they failed one at a time then it'* the bulbs...
