i had to replace the bulbs on my neighbors avalanche with a different version relating to a service bulletin from gm. its also listed that the plug needs to checked for damage due to the related issue. something regarding the bulbs are being overpowered and overheating the bulbs and sockets. id have to go back and reread the article on the subject but possibly something to look into. i apologize if im mistaken and it was only avalanche related but it sounds similar so wanted to add input here.
