2016 BMW X4 headlight bulb fitment varies by the installed headlamp assembly. The low beam is listed as either D1S or LED, while the high beam is also listed as D1S or LED. Match the replacement to the existing headlight type rather than assuming the two systems use the same serviceable bulb.
The fog lights, daytime running lights, parking lights, tail lights, rear side markers, center stop light, and license plate lights are listed as LED applications. Front turn signal fitment depends on the headlights: use 7507 with HID headlights or LED with LED headlights. The rear turn signal uses 7507.
