I have the Slot-It three car set of the Rothmans 956C Porsche but car #1 has the left headlight glued on upside down. I guess someone had a bad day at the factory. They are one of my favorite cars and I love looking at them but it really bothers me that the light is upside down. I don't want to take it apart because the light is probably glued on and I will probably break it if I try taking it apart. Should I just leave it alone? Can I, should i fix it? I'm sure the set loses some value because of it.

Fixing it or not depends on what you want to do with it. If you want to keep it for yourself and you don't like the light upside down fix it. If you plan to one day sell it then the light being upside down may increase its value as a rare imperfection (think of the those coins and stamps miss printed/minted) I would guess you taking the light apart and having to reglue it may impact on its value as you wouldn't be able to say it was mint in box.

As you say, it bothers you, so if you have the ability, I'd say fix it.

IMO, a one-off error such as this doesn't add any collector value. It's a blemish that reduces the value.
