Honda Odyssey Side Marker Bulb Size

Additional Notes

• The Honda Odyssey front side marker uses five distinct bulb types across its model years: 194, 168, 3357NA, 3457NA, 194NA, 1157NA, 1034NA, and 2057, reflecting significant variation across generations.
• The 194 bulb is a T10 miniature wedge type rated at 12V and 3.78W, and it fits the Honda Odyssey front side marker position for the 2021-2024 model years.
• The 168 bulb shares the same T10 wedge form factor as the 194 but draws more power at 4.9W. Despite the physical similarity, the two are not rated identically and serve different model years on the front side marker position.
• The 3357NA and 3457NA bulbs are both T25 wedge types with natural amber glass, but they differ in filament count. The 3357NA is a single-filament bulb rated at 27W, while the 3457NA is a dual-filament bulb rated at 27W and 7W. These are not interchangeable despite sharing the same voltage, glass color, and base style.
• The 194NA is a natural amber glass variant of the standard 194 bulb, sharing the same T10 wedge base and 3.78W rating. It fits the front side marker on the 2005-2007 Odyssey, whereas the clear 194 is used on 2021-2024 models.
• The 1157NA and 1034NA bulbs both use a BAY15d bayonet base and carry natural amber glass, but they are listed as distinct sizes. The 1034NA is noted as a variant of the 1157 and appears on the 1999-2001 and 2003 Odyssey front side marker, while the 1157NA appears on the 2002 and 2004 model years.
• The 2057 bulb is a dual-filament BAY15d bayonet type rated at 26.9W and 8W, described as a brighter variant of the 1157. It fits the front side marker on the 1995-1998 Odyssey.
• The rear side marker position on the Honda Odyssey uses a single bulb type, the 7443, across all listed model years from 1995-2013. The 7443 is a T20 dual-filament wedge bulb rated at 12V with outputs of 21W and 5W.
• The T25 bulbs used in the front side marker position, specifically the 3357NA for 2011, 2017-2018 and the 3457NA for 2012-2016, are physically larger than the T10 bulbs used in other years and are not compatible with sockets designed for the smaller wedge base.
• The natural amber glass designation on bulbs such as the 3357NA, 3457NA, 194NA, 1157NA, and 1034NA indicates that the amber color is produced by the glass envelope itself rather than by a colored lens in the vehicle housing, which is a relevant distinction for replacement fitment.
