Honda Odyssey Headlight Bulb Size

Additional Notes

• The 9005 bulb is the high beam fitment for the Honda Odyssey across 2005-2020, making it the most consistently used bulb type in these specifications. It is a single-filament halogen bulb operating at 12V and 65W with a P20d base, built to the ANSI standard used in the US and Canada.
• The 9003 bulb served both the high beam and low beam positions on the Honda Odyssey from 1995-2004. It is a dual-filament halogen bulb with a P43t base rated at 12V and 60W/55W, where the higher wattage filament handles high beam output and the lower handles low beam output within a single housing.
• Because the 9003 handles both beam functions through two filaments, the 1995-2004 Odyssey used a single bulb per headlight assembly rather than separate high and low beam bulbs.
• From 2011-2020, the low beam position on halogen-equipped models uses the H11 bulb. It is a single-filament halogen bulb with a PGJ19-2 base rated at 12V and 55W, following the ECE standard, though it also carries US approval.
• The D2S is a high-intensity discharge xenon bulb used in the low beam position on HID-equipped Honda Odyssey models from 2011-2018. It operates at 85V and 35W and requires an external ignitor to initiate the arc discharge. Its P32d-2 base is designed specifically for projector-type housings.
• The D2S and H11 low beam fitments are not interchangeable. The D2S requires a projector housing and an external ignitor, while the H11 is a standard halogen bulb. On 2011-2018 models, the correct low beam bulb depends on whether the vehicle was built with halogen capsule headlamps or HID headlamps.
• The 9005 high beam bulb is not listed with an HID variant for any model year, meaning HID-equipped 2011-2018 Odyssey models used a 9005 halogen bulb for the high beam alongside the D2S xenon low beam.
• The 9006 bulb served as the low beam fitment from 2005-2010. It is a single-filament halogen bulb with a P22d base rated at 12V and 55W, following the ANSI standard. Although the 9005 and 9006 share similar wattage and voltage ratings, their bases differ and they are not directly interchangeable.
• The P20d base of the 9005 and the P22d base of the 9006 are physically distinct, which prevents cross-fitment between the high beam and low beam sockets on 2005-2010 models despite both bulbs operating at 12V and 55W-65W.
• The transition from the dual-filament 9003 to separate 9005 and 9006 bulbs occurred between the 2004 and 2005 model years, reflecting a shift from a single-bulb-per-housing design to a dedicated two-bulb headlight system.
