The typical setup on a 2009 Honda Accord with standard headlights uses H11 low-beam bulbs and 9005 high-beam bulbs. If your model has factory HID headlights, the bulbs are different (D2S or D3S) and require a ballast. Fog lights, when equipped, commonly use H11, though some trims used alternative bulb types. Confirm by checking the bulb in your headlight or the owner's manual.
Halogen headlights: standard configuration
The following bulb types cover the common halogen arrangement found on many 2009 Accords. These apply to most LX, EX, and EX-L trims unless HID or alternate lighting was installed.
- Low beam bulbs: H11
- High beam bulbs: 9005 (HB5)
- Fog light bulbs: commonly H11 on many trims; some trims use H16 or H3—verify in your owner's manual
When replacing halogen bulbs, choose replacements within the same wattage class and color temperature to preserve beam pattern and safety. If your car uses projector headlights, the same H11 low-beam type generally applies, but confirm with the manual.
HID headlights (factory option on some trims)
About a subset of 2009 Accord models were equipped with factory HID headlights. These use ballast-based bulbs that are not interchangeable with halogen units.
- Bulb type: D2S or D3S (depending on the ballast system)
- Note: If you have HID, replacement bulbs are part of the HID assembly and are not simply halogen bulbs
To confirm whether your car has HID headlights, look for a ballast module near the headlight housing, or check the original window sticker or owner's manual. If unsure, a trusted parts retailer can verify the correct bulb type from your VIN.
How to tell if you have HID headlights
HID systems use a ballast and a specialized bulb. The headlight assembly will typically have a ballast box and a wiring harness connected to a D2S or D3S bulb. If your headlamp uses a removable halogen bulb under a standard housing, you likely do not have HID.
Practical tips for choosing bulbs
Besides the base bulb type, consider color temperature and quality. Most drivers prefer about 4300K to 5000K for a bright, white light that preserves visibility without excessive glare. Higher color temperatures (e.g., 6000K) can appear bluish and may reduce visibility in rain or snow. Ensure any aftermarket bulbs comply with local laws and fit your vehicle's specifications.
Summary
For most 2009 Honda Accords with halogen headlights, you will typically need H11 for low beams and 9005 for high beams, with fog light bulbs often being H11 (though some trims use H16 or H3). If your Accord has the factory HID option, expect D2S or D3S bulbs paired with a ballast. Always verify the exact requirement by inspecting the current bulbs or consulting the owner's manual or a knowledgeable parts retailer to ensure compatibility.
