The problem with car parts is you will probably need to have to have

If it came off the same assembly line with the same part number, it's the

In theory, it is possible that parts go through a post-manufacturing QA
sorting process, and only those which meet some higher standard get sold to
the aviation market.

On the other hand, in practice, I strongly suspect a light bulb is a light
