Knowing the correct headlight bulb type before you buy saves a trip back to the parts store. Honda used halogen and LED headlight systems across Civic generations sold in the U.S., and the bulb type varies not just by generation but by trim level and model year within the same generation. This reference covers every U.S.-market Honda Civic headlight bulb type from the 7th generation (2001–2005) through the 11th generation (2022–2025), including low beam, high beam, and fog light fitments, and aftermarket compatibility notes.
Bulb Type Reference Guide
Before reading the tables: 9003 (H4) is a dual-filament bulb that handles both low and high beam from a single unit. H8, H11 are single-filament halogen bulbs sharing the same PGJ19 base family — H8 and H11 are physically similar but not interchangeable; always match the exact type. 9005 (HB3) and 9006 (HB4) are single-filament halogen bulbs used for high beam and low beam respectively in separate-bulb housings. LED units on OEM applications are sealed assemblies and are not individually replaceable without replacing the entire housing. Aftermarket LED conversion bulbs can be installed in halogen housings but require CANBUS adapters on 10th gen Civics to prevent error codes.
7th Generation (2001–2005)
| Trim | Low Beam | High Beam | Fog Light | System |
|---|---|---|---|---|
| LX sedan/coupe (2001–2003) | 9003 (H4) (dual-beam) | 9003 (H4) (shared) | Not equipped | Halogen |
| EX sedan/coupe (2001–2003) | 9003 (H4) (dual-beam) | 9003 (H4) (shared) | H11 | Halogen |
| HX coupe (2001–2003) | 9003 (H4) (dual-beam) | 9003 (H4) (shared) | Not equipped | Halogen |
| Si hatchback EP3 (2002–2003) | 9003 (H4) (dual-beam) | 9003 (H4) (shared) | H11 | Halogen |
| LX sedan/coupe (2004–2005) | 9006 (HB4) | 9005 (HB3) | Not equipped | Halogen |
| EX sedan/coupe (2004–2005) | 9006 (HB4) | 9005 (HB3) | H11 | Halogen |
| Si hatchback EP3 (2004–2005) | 9006 (HB4) | 9005 (HB3) | H11 | Halogen |
The 7th gen split into two distinct headlight configurations mid-generation. The 2001–2003 models use a 9003 (H4) dual-filament bulb — one bulb per side handles both low and high beam via a dual-filament design. This is a common source of ordering errors: owners of early 7th gen Civics who search by generation rather than year often receive the wrong 9006/9005 pair. The 2004–2005 facelift switched to a separate-bulb housing with 9006 low beam and 9005 high beam. All 7th gen Civics are halogen only. Fog lights were standard on EX and Si trims; LX and HX did not have fog lights from the factory.
8th Generation (2006–2011)
| Trim | Low Beam | High Beam | Fog Light | System |
|---|---|---|---|---|
| LX sedan/coupe | 9006 (HB4) | 9005 (HB3) | Not equipped | Halogen |
| EX sedan/coupe | 9006 (HB4) | 9005 (HB3) | H11 | Halogen |
| EX-L sedan/coupe | 9006 (HB4) | 9005 (HB3) | H11 | Halogen |
| Si sedan/coupe (FG2/FA5) | 9006 (HB4) | 9005 (HB3) | H11 | Halogen |
The 8th gen is all-halogen across every U.S.-market trim. Despite what some aftermarket listings suggest, the USDM 8th gen Civic EX-L did not receive factory HID headlights — that equipment was reserved for Acura models sharing the same platform (TSX, RDX) and for Honda Odyssey. The 8th gen Civic uses 9006 low beam and 9005 high beam on all trims, with H11 fog lights on EX, EX-L, and Si. The coupe and sedan use different front turn signal connectors but the same headlight bulb sizes. Note that 2008–2012 coupes use H11 for the low beam per some fitment guides — verify your specific build year and body style before ordering, as coupe and sedan headlight housings differ.
9th Generation (2012–2015)
| Trim | Low Beam | High Beam | Fog Light | System |
|---|---|---|---|---|
| LX sedan/coupe | 9006 (HB4) | 9005 (HB3) | Not equipped | Halogen |
| EX sedan/coupe | 9006 (HB4) | 9005 (HB3) | H11 | Halogen |
| EX-L sedan/coupe | 9006 (HB4) | 9005 (HB3) | H11 | Halogen |
| Si sedan/coupe (2012–2013) | 9006 (HB4) | 9005 (HB3) | H11 | Halogen |
| Si sedan/coupe (2014–2015) | H11 (sedan) / 9006 (coupe) | 9005 (HB3) | H11 | Halogen |
The 9th gen is all-halogen across every U.S.-market trim. No factory HID or LED headlights were offered on any USDM 9th gen Civic. The 9006/9005 split applies to all trims for 2012–2013; the 2014–2015 late refresh introduced a body-style split on the Si where the sedan uses H11 for the low beam while the coupe retains 9006 — a documented fitment difference that causes ordering errors. The 9th gen headlight housing is known for moisture intrusion due to a weak seal AT the housing seam. Moisture inside the housing accelerates bulb degradation and can damage wiring connectors. Resealing the housing with butyl rope sealant is a common preventive measure before bulb replacement.
10th Generation (2016–2021)
| Trim | Low Beam | High Beam | Fog Light | System |
|---|---|---|---|---|
| LX sedan/coupe | H11 | 9005 (HB3) | Not equipped | Halogen |
| Sport sedan/coupe | H11 | 9005 (HB3) | H8 | Halogen |
| EX sedan/coupe | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| EX-L sedan/coupe | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| Touring sedan/coupe | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| Si sedan/coupe | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| Type R FK8 | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| Sport Hatchback | H11 | 9005 (HB3) | H8 | Halogen |
| EX / EX-L / Touring Hatchback | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
The 10th gen is the first Civic generation to offer full LED headlights as standard equipment, starting at the EX trim. The LX and Sport trims retained halogen with a projector housing — H11 for the low beam and 9005 for the high beam as separate bulbs. This is a change from the 9006/9005 split used in 8th and 9th gen: the 10th gen halogen housing uses H11 low beam, not 9006. Fog lights on halogen Sport trims use H8, not H11 — H8 and H11 share the same base family but are not interchangeable; ordering H11 for a 10th gen Sport fog light is a common mistake. The EX and above LED assemblies are sealed units; individual LED elements are not replaceable. A failed LED headlight assembly on a 10th gen EX or above requires full housing replacement. OEM Honda LED assembly: approximately $400–$600 per side. Aftermarket alternatives from TYC and Depo are available at lower cost but vary in beam pattern quality. Before replacing a failed LED assembly, inspect the harness connector for corrosion — connector corrosion is a documented cause of LED headlight failure on 10th gen Civics that does not require housing replacement.
11th Generation (2022–2025)
| Trim | Low Beam | High Beam | Fog Light | System |
|---|---|---|---|---|
| LX sedan | LED (sealed assembly) | LED (sealed assembly) | Not equipped | Full LED |
| Sport sedan/hatchback | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| EX sedan/hatchback | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| Sport Touring sedan/hatchback | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| Si sedan | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| Type R FL5 | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
| Hybrid EX / Sport Touring | LED (sealed assembly) | LED (sealed assembly) | LED (sealed assembly) | Full LED |
The 11th gen standardized full LED headlights across every trim, including LX and Sport — a significant change from the 10th gen where those trims used halogen. No halogen headlight option exists on any 11th gen Civic sold in the U.S. All lighting is factory LED sealed assemblies: headlights, DRLs, fog lights where equipped, and turn signals. The 11th gen LED housing design is not interchangeable with the 10th gen despite the similar trim structure. Fog lights are not equipped on the LX trim; all other trims include LED fog lights. Automatic high beams are standard across all 11th gen trims as part of Honda Sensing.

Aftermarket Upgrade Notes
Halogen to LED conversion (7th–10th gen LX/Sport): Drop-in LED conversion bulbs are available for 9003, 9006, 9005, H11, and H8 sockets. On 10th gen Civics, the CANBUS system monitors bulb resistance and will trigger a “check bulb” warning if the LED draws significantly less current than the OEM halogen. A CANBUS-compatible LED bulb or an inline resistor/decoder eliminates this. Brands with documented CANBUS compatibility on 10th gen Civics: Morimoto 2Stroke 3.0, Diode Dynamics SL1, GTR Lighting Ultra 2. Avoid no-name LED bulbs — beam pattern quality and CANBUS compatibility are inconsistent.
10th/11th gen LED assembly failure: OEM LED assemblies on EX and above trims (10th gen) and all trims (11th gen) are sealed units. Individual LED elements cannot be replaced. A failed DRL, low beam, or high beam LED element requires full housing replacement. Before replacing the housing, check the headlight control module and Wiring Harness connector — corrosion at the connector is a documented cause of LED headlight failure on 10th gen Civics that does not require housing replacement.
Headlight Bulb Type — Quick Reference:
☐ 7th gen 2001–2003: all trims use a single 9003 (H4) dual-filament bulb per side for both low and high beam. Do not order 9006/9005 for these years — they will not fit.
☐ 7th gen 2004–2005: switched to separate 9006 low beam and 9005 high beam. No HID or LED available from the factory on any 7th gen Civic.
☐ 8th gen (2006–2011) and 9th gen (2012–2015): all USDM trims use halogen only. 9006 low beam and 9005 high beam on all trims. No factory HID on any USDM Civic of these generations.
☐ 9th gen 2014–2015 Si: low beam differs by body style — H11 on sedan, 9006 on coupe. Verify body style before ordering.
☐ 10th gen LX and Sport: H11 low beam and 9005 high beam — separate bulbs in a projector housing. Do not order 9006 for these trims; it will not fit. Fog lights on Sport trims use H8, not H11.
☐ 10th gen EX and above: full LED sealed assemblies. Individual bulbs are not replaceable. A failed LED element requires full housing replacement.
☐ 11th gen (2022–2025): full LED sealed assemblies on every trim including LX and Sport. No halogen option exists. No bulb replacements are possible — any headlight failure requires housing replacement.
☐ Fog lights: H11 on 8th and 9th gen EX, EX-L, and Si halogen trims. H8 on 10th gen Sport halogen trims. LED sealed on all 10th gen EX and above and all 11th gen Sport and above. LX trims across all generations do not have fog lights.
☐ 10th gen halogen-to-LED conversion: use a CANBUS-compatible LED bulb (Morimoto 2Stroke 3.0, Diode Dynamics SL1, GTR Lighting Ultra 2) to prevent “check bulb” warning codes. Generic LED bulbs frequently trigger CANBUS errors on 10th gen Civics.
☐ 10th gen LED assembly connector corrosion is a documented cause of headlight failure that does not require housing replacement. Inspect and clean the harness connector before ordering a replacement assembly.
