I've brought this up before with others also . I purchased a beautiful black 05 XLR in Palm Springs , shipped it up to BC , Canada and could not pass federal / provincial inspections due to 1/2 the passenger tail light not working properly. We called GM canada , used auto wreckers that couldn't guarantee the condition or if the light even worked for $800 . Thought I had a new one ordered on Amazon marketplace new for $700 , said they had delivered it , it never showed up as soon as I asked about it they said it was lost/damaged and refunded our money back ( we lost about $80 in US back to Canadian funds) missed the inspection period while waiting and had to reinspect for another $140 after I was finally so desperate I happened to ask a friend of mine and he said his buddy might be able to fix it in his garage (electronic guy / electrician ? ) They heated it up carefully , pulled the red plastic off to get at the LEDs . the LEDs ended up being $0.60 each . While we were waiting to get this fixed we had a number of "feelers" out there trying to help us . We did end up buying a NEW passenger IMPORT light but the left strip of lights is in amber and its a 5 pin plug not a 4 pin like ours. He is working on changing the LEDs to red as I type this so hopefully I will have 2 that work. Here is some pics he sent me while working on the first one , the LEDs we used that were close to the same color / brightness , trying a few different LEDs for brightness then the finished product. The riskiest thing is getting the red plastic off without damaging it , the rest was fairly easy he said.
