This part is listed by BMW as BMW part number 63126907489 (63-12-6-907-489) and is described as Xenon Headlight Igniter for E60 E65 X5 Z4. 

If your Xenon headlight igniter fails, then your your HID bulb won't be able to fire, leaving you with a headlight that won't work. These headlight igniters are a common failure item on the early E60 5 Series (2004 and 2005), early E65/E66 7 Series (2002 thru 3/2005 production), first generation X5 from 2004 to 2006, and first generation Z4 (2003 to 2008.) If you've already checked or replaced your Xenon bulb,  but your headlight still won't light up, we suggest checking or replacing this igniter next.
