Holding the bulb for the interior reading light, this Original BMW bulb socket fits a long run of BMW cars and SUVs, from the 1999 3 Series through 2019 6 Series Gran Coupe models. BMW's part name is Bulb socket, and it is sold individually under part number 63-25-8-389-736. Each socket weighs 10 g (0.35 oz) and is made in the United Kingdom. BMW shows production starting in October 1995. A bulb socket carries power to the bulb and holds it in position in the lamp housing, so a cracked or loose socket can leave the light dead even when the bulb is good.
