The E90 3 Series (2005–2013) offers multiple headlight configurations, so bulb types vary by trim: halogen, Xenon HID (Bi‑Xenon), or, in rare cases, LED upgrades. In short, halogen headlights use H7 for low beams and H1 for high beams, Xenon HID headlights use D2S or D3S bulbs depending on year and ballast, and fog lights are typically H8 (market-dependent). LED setups, when present, use non-replaceable modules rather than traditional bulbs. This article breaks down the common bulb types by configuration and how to identify the correct ones for your car.
Headlight configurations
Halogen headlights
For E90 models with standard halogen headlights, the most common bulb types are listed below.
- Low beam: H7
- High beam: H1
- Front fog lights: commonly H8 (some markets use H11)
Bulb availability varies by market and trim. To be certain, check the bulb you remove from the socket or consult the owner’s manual for your exact build date and market.
Xenon headlights (Bi‑Xenon HID)
For E90s equipped with factory Xenon headlights, the bulbs are HID rather than halogen, and the exact type depends on the year and ballast configuration.
- HID bulbs: D2S or D3S (which one your car uses depends on year/trim and the ballast system)
- Bi‑Xenon functionality: the same HID bulb provides both low and high beam via a moving shield; there is typically no separate high-beam bulb in Bi‑Xenon setups
If your car has adaptive or advanced headlight features, confirm the correct bulb type and ballast compatibility with the manual or a dealer, as replacements must match the original configuration.
LED headlights and verification
LED headlight installations were not standard on most E90s. Some vehicles may have aftermarket LED retrofit kits, in which case the headlight assemblies and wiring differ from stock bulbs, and replacement procedures vary. Always verify whether your E90 uses stock halogen, Xenon HID, or an aftermarket LED setup before purchasing bulbs.
Summary
The BMW E90’s bulb types depend on the headlight configuration: halogen models use H7 for low beam and H1 for high beam, with front fog lights commonly being H8 (market-dependent); Xenon Bi‑Xenon models use D2S or D3S HID bulbs depending on year and ballast; LED-equipped versions are uncommon and usually involve modules rather than replaceable bulbs. Always confirm the exact bulb type by consulting the owner’s manual, checking the ballast label, or asking a qualified technician if you’re unsure.
