In most 2004 Honda Odyssey models, the headlight bulbs are 9006 for the low beam and 9005 for the high beam, with fog lights typically using H11 if your trim includes them. Exact sizes can vary by market and trim, so check your owner’s manual or inspect the bulb to confirm.
Headlights: common configurations you may encounter
The Odyssey’s headlight setup varies by region and trim. While many US-spec models use separate bulbs for low and high beams, some markets used an all-in-one H4-style bulb. Below are the two widely reported configurations you might find.
- Low beam: 9006 (HB4) for US-spec models
- High beam: 9005 (HB3) for US-spec models
In non-US markets or for certain trims, a dual-filament H4 (HB2) bulb may be used instead of separate 9006/9005 bulbs. Always verify based on your vehicle’s VIN and trim.
Fog lights: when your Odyssey has them
Fog lights, if equipped on your 2004 Odyssey, typically use H11 bulbs. This is common for many Honda models from that era, but some trims may not include fog lights at all or may use different lamp configurations.
- Fog light bulb: H11
If you’re not sure whether your vehicle has fog lights or which bulb size to buy, consult the owner’s manual or remove the fog light bulb to read the size stamped on the base.
Other exterior bulbs: what to expect
Turn signals, brake lights, and reverse lights can vary by trim and region, and their exact bulb types aren’t universal across all 2004 Odysseys. The safest approach is to check the specific bulb from the assembly or refer to the official documentation for your vehicle.
How to verify the exact bulb size on your vehicle
To ensure you get the correct replacement, use one of these methods:
- Consult the owner’s manual for the bulb type and replacement procedure.
- Inspect the bulb base on the current bulb or the back of the headlight assembly for size markings.
- Use your VIN to look up exact part numbers in Honda’s parts catalog or with a dealer.
Verifying the precise bulb size is especially important if you own a European or Canadian-spec Odyssey, where configurations can differ from the US market.
Summary
For a 2004 Honda Odyssey, headlight replacements are commonly 9006 for low beams and 9005 for high beams, with fog lights typically using H11 when equipped. Given regional and trim variations, always confirm using the manual, the bulb itself, or a parts lookup by VIN to ensure an exact fit.
