BMW 3 Series F30 bulb types

Base halogen spec; many have xenon/LED

• Dip beam (low)H7VerifiedBase halogen headlamp variant. Bi-xenon-equipped cars use D1S instead.
• Main beam (high)H7VerifiedBase halogen headlamp uses H7 for both dip and main beam; xenon/D1S only on optional adaptive headlight variant.
• Front fogH8VerifiedH8 listed as primary fog bulb by both sources; H11/D1S variants also sold but H8 is the standard fitment.
• Sidelight / DRLH6WVerifiedH6W (BAX9s) parking light in halogen headlamps; birnen-typ and mk-led.hr agree. DRL ring in halogen lamps is PW24W (mk-led). Xenon/LED headlamp variants have LED position lights (youcanic chart says LED).
• Front indicatorPY21WVerifiedAmber bulb in clear headlamp-integrated indicator lens; confirmed by both sources.
• Rear indicatorP21WVerifiedOften listed as PY21W elsewhere — birnen-typ explicitly lists Blinker hinten as P21W (clear bulb behind amber-tinted rear lens), not PY21W. Autodoc F30 indicator catalogue also lists P21W as a fitment for this vehicle.
• Brake / tailP21WVerifiedSingle-filament P21W (UK 382) brake; tail is an LED strip in the cluster. Autodoc rear-lamp UNIT specs list LED + P21W + H21W (H21W = rear fog, pre-LCI) only; P21/5W and P21/4W come from autodoc's catch-all bulb category, not the lamp spec. youcanic lists 1156 (=P21W).
• ReverseP21WVerifiedbirnen-typ lists Rückfahrlicht as P21W or H21W depending on variant; P21W is the primary/base value. H21W appears on some LCI/facelift lamp clusters.
• Rear fogH21WVerifiedOften listed as P21W elsewhere — birnen-typ gives Nebelschlussleuchte as H21W or LED (not P21W); autodoc reverse/rear-fog listing supports a distinct type.
• Number plateLED (non-replaceable)VerifiedFactory LED number plate units on all F30/F31 (birnen-typ and youcanic agree; autodoc rear-lamp listings show no plate bulb). Autodoc C5W/C10W/W5W entries are catch-all category noise, not F30 spec.
