Absolutely get it replaced - the burnt out area will just continue to get bigger as the soldered joints continue to deteriorate and the customer pay cost after the warranty has expired is huge. Tesla has replaced a ton of them under warranty and probably next to none as customer pay. I noticed that the replacements in my car were the exact same part number although I believe they were made by Varroc in Romania instead of Mexico so maybe they are improved. It's telling that lights are excluded from the Extended Service Agreement - Tesla knows they will fail.
