In US-spec 2004 Honda Odyssey models, the headlight system uses separate bulbs for low and high beams. The typical configuration is low-beam H11 and high-beam 9005, though regional variations exist and some markets used different setups.
Common bulb types in the 2004 Odyssey
Headlight bulb configurations can vary by market and trim. The following list covers the most common configuration for US-spec Odysseys from this era.
- Low-beam bulb: H11 (55W)
- High-beam bulb: 9005 (HB3, 65W)
Some markets or older stock may use alternative arrangements, such as a dual-beam H4 setup in certain configurations. Always verify by checking the installed bulb or the owner's manual.
How to confirm and replace
To be sure you’re purchasing the correct bulbs and to replace them safely, follow these steps:
- Open the hood and locate the headlight assembly; remove the dust cover if applicable to access the bulb.
- Disconnect the electrical connector from the bulb and rotate the bulb socket counterclockwise to release it from the housing.
- Remove the bulb and inspect markings or packaging to confirm you have H11 for low beam or 9005 for high beam.
- Install the replacement bulb, reseat the socket in the housing, reconnect the wiring, and replace the dust cover.
- Test the headlights to verify proper operation and alignment; replace in pairs for balanced illumination.
Important: Handle halogen bulbs with clean hands or gloves to avoid oils that can shorten bulb life.
Regional variations
Even within the United States, there can be variations by trim level, production year, or dealership practice. If you’re unsure, the safest approach is to remove the current bulb and compare its base to standard references (H11 vs 9005) or consult the owner's manual or a trusted parts catalog.
Summary
The 2004 Honda Odyssey generally uses separate low- and high-beam halogen bulbs, with H11 for low beam and 9005 for high beam in many US-spec models. Confirm by inspecting the current bulb or consulting the manual, and replace bulbs in pairs for best results.
