I know the halogen low beam bulb is H7, but does anyone know what the socket size of the other end of the adapter is?

IIRC the low beam connection is a 9006 connection.

Fyi if you are looking for a replacement low beam socket adapter I think the part # is 63126904051 (the high beam should be 63126904050).

Also iirc the high beam is a 9005 plug vs the low beam 9006 plug. The two are slightly different because of the tabs inside the plug (see pic). Note the pic is of a 9005 and 9006 bulb NOT e39 specific bulb holders (which will be slightly different), but the detail about the tabs is what I am trying to illustrate.


Great info! Thanks!!
