Halogen headlights commonly used on 2009 Accords require H11 for the low beam and 9005 for the high beam. If your Accord is equipped with factory HID headlights, the low beam uses a xenon bulb such as D2S (with some markets using D3S), and the high-beam arrangement may differ by trim. Always verify with your owner's manual or the label on the headlight housing.
Halogen headlights (most 2009 Accords)
This section covers the typical sizes used when the car has standard halogen optics, with separate bulbs for low and high beams.
- Low beam: H11 (12V, typically 55W)
- High beam: 9005 (HB3) (12V, typically 65W)
Halogen bulbs are bulb-and-socket replacements that are generally straightforward, but it's important to confirm the exact bulb size for your specific trim and region.
Factory HID headlights (optional on some trims)
For models equipped with factory HID headlights, the headlight bulbs are xenon and require a ballast. The common bulb style for the low beam is D2S, with some variants using D3S depending on the assembly and market. The high-beam, if any, may be a separate HID or a halogen bulb depending on the version.
- Low beam: D2S (commonly) or D3S (in some variants)
- High beam: May be another HID ballast setup or a separate halogen bulb, depending on trim
HID bulbs require proper handling and a compatible ballast. Replace bulbs according to the manual, and consider professional servicing if you’re unsure.
How to confirm which system you have
Check the owner’s manual, inspect the headlight housing label, or verify on a build sheet. The steps to replace bulbs differ between halogen and HID systems, and using the wrong bulb can damage the headlight or void warranties.
Summary
In summary, the typical 2009 Accord with halogen headlights uses H11 for the low beam and 9005 for the high beam. If your car has factory HID headlights, the low beam bulb is usually D2S (with D3S used in some variants), and the high-beam configuration depends on the specific headlight assembly. Always verify with the manual or the housing label for your exact trim and market.
