Air bag light

The retractor is hidden part that the seat belt reels up on, not the buckle. You have to buy the retractor and the whole seatbelt as an assembly. If you don’t know what you are doing, then you should get someone else to do it. There are explosives in the retractor, usually. (In an accident the explosives fire to pull the seat belt tight on you.)
