“Just blew out my rear turn signal light. Yes, I'm a turn signal user. I wish there were more of us out there. I took a peek to see how hard it would be to make the replacement and walked away with the though that GMC may have welded the lights into the chassis. So I did a BING search and found this sight with a great "how to" video. Thanks Car Care Kiosk. ”
