These new old stock Plug terminals for tail light are a rare find, as they are no longer available. These connectors plug into the back of the rear lights (square tail lights) and can corrode due to water leaks causing malfunction of the light or lights.For those of you struggling with this common issue, this is the perfect OEM solution to address the problem. Price is per connector. and they are also used in some E12 and E24 models.
