My middle brake light(the one at the top of tailgate) is out, and I was wondering if there is a way to fix it or do you have to replace the whole thing. I have a 2004 Tahoe. When I took the light off I couldn't see anywhere that the light can come apart the light is plastic welded together. Looking online the lights as a whole are around $150us which I think is a liitle costly. If someone might have come across this problem and knows a way to fix it would be greatly appreciated.
