What size headlight bulb for 2004 Honda Odyssey?

The 2004 Honda Odyssey generally uses two separate bulbs for its headlights: 9006 for the low beam and 9005 for the high beam.

In most US-spec Odysseys from that year, the low-beam bulb is a 9006 (HB4) and the high-beam bulb is a 9005 (HB3). Bulb sizes can vary by market or revision, so it’s wise to verify by checking the bulb you remove or consulting the owner's manual if you’re outside the United States or if your specific trim differs.

Standard bulb sizes for the 2004 Odyssey

Before listing the sizes, note that this reflects the typical configuration found on US-market 2004 Odysseys with separate low/high beams.

• Low beam: 9006 (HB4)


• High beam: 9005 (HB3)

These sizes cover the most common replacement scenarios for the 2004 Odyssey. If your vehicle uses a different setup due to market specifications or a mid-year revision, sizes may differ.

How to confirm the exact bulb size on your vehicle

To ensure you buy the correct bulbs, use these verification steps.

1. Check the owner's manual for bulb specifications for your exact market and trim.


2. Carefully remove the existing headlight bulb and read the markings on the base or the bulb itself.


3. Match the markings or part number to a reputable parts retailer or the original packaging.


4. If in doubt, bring the old bulb to the store to compare in person or order a twin-pack to cover both high and low beams.

For replacement, many drivers opt for standard halogen bulbs from reputable brands and consider upgrading to brighter, yet legally compliant, options if permitted in their area.

Other considerations

Note that fog lights, if equipped, use separate bulbs (commonly H11) and are not part of the main headlight bulb sizes discussed here. Always handle bulbs with clean gloves to avoid oil on the glass, which can shorten bulb life.

Summary: On a typical 2004 Honda Odyssey, you’ll most commonly need a 9006 bulb for the low beam and a 9005 bulb for the high beam. Confirm with your manual or by inspecting the current bulbs, as regional variations or mid-year revisions can change the exact sizes.
