Honda Odyssey brake bulb sizes include 7440 and 7443 for outer brake applications, with 921 and 168 bulb sizes specified for the center high mount stop light. The replacement chart covers vehicle production years spanning 1995 through 2024.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Odyssey brake lights use two bulb types across its model years: the 7440 and the 7443. Both are T20 wedge-format bulbs operating at 12V, and both share the same single-filament wattage of 21W. The key distinction is that the 7443 carries a second filament rated at 5W, making it a dual-filament bulb, while the 7440 is single-filament only.
Because the 7440 and 7443 share the T20 wedge base, they are physically similar, but the difference in filament count means they are not interchangeable without consequence. Installing a single-filament 7440 in a socket designed for the dual-filament 7443 would result in the loss of one lighting function.
The Honda Odyssey (2014-2024) uses the 7440 for its brake lights, while model years 1995-2013 use the 7443.
The same filament-count distinction applies to the Outer Brake position. The 7440 is specified for 2014-2020, and the 7443 covers 1995-2013.
The Center High Mount Stop Light on the Honda Odyssey uses a separate bulb type from the main brake and outer brake positions. Model years 1999-2018 use the 921, a T15 wedge bulb rated at 12V and 16W.
For the 1995-1998 Center High Mount Stop Light, the specified bulb is the 168, a T10 miniature wedge bulb rated at 12V and 4.9W. This is a notably lower wattage than the 921 used in later years, and the two types are not interchangeable due to their different base sizes and wattage ratings.
All four bulb types referenced across these specifications, the 7440, 7443, 921, and 168, conform to ANSI standards applicable in both the United States and Canada.
The 921 bulb used in the Center High Mount Stop Light is a single-filament T15 wedge type. Its 16W output places it between the low-wattage 168 and the higher-output T20 brake bulbs used elsewhere on the vehicle.
