3rd Brake Light housing
Having replaced my interior 3rd brake light with factory spoiler I now have a perfectly good housing for anybody who needs it. Just pay shipping and it's yours. Note, this does not include the wiring. It's literally just the housing, and the cover that goes over it (black)
If you've never replaced yours odds are you need to since it's probably melted to some extent.
It runs 100% of the time 80% of the time.
