Honda Odyssey Parking Light Bulb Size

Additional Notes

• The 3457NA bulb is the most frequently specified front parking light across the Honda Odyssey's model history, covering the 2011, 2013-2016, and 2018 model years. It is a dual-filament wedge bulb in the T25 form factor, rated at 12V with a 27W high filament and 7W low filament, and features natural amber glass.
• The 2357NA bulb is specified for the 2021-2024 Honda Odyssey front parking light. It uses a BAY15d bayonet base rather than a wedge-style base, operates at 12V with filaments rated at 26.9W and 8W, and incorporates natural amber glass.
• The BAY15d bayonet base is a two-pin offset base design that physically prevents incorrect installation orientation. This base type appears across several bulbs in the Odyssey's history, including the 2357NA, 1034NA, 1157NA, and 2057.
• The 3357NA, specified for the 2012 and 2017 model years, shares the T25 wedge form factor with the 3457NA but is a single-filament bulb rated at 27W. Despite the physical similarity, the 3357NA and 3457NA are not interchangeable due to the filament count difference.
• The 7444NA, specified for the 2019-2020 Honda Odyssey with halogen capsule headlamps, is a dual-filament T20 wedge bulb rated at 21W and 5W. The T20 wedge base is a different physical size from the T25, making it incompatible with sockets designed for T25 bulbs.
• The "NA" suffix present on several bulb designations, such as 2357NA, 3457NA, and 194NA, indicates natural amber glass coloring. This amber tint is built into the glass envelope rather than applied as a coating, producing the amber light output required for parking and turn signal functions in many markets.
• The 1034NA, specified for the 1999-2001 and 2003-2004 model years, is described as a variant of the 1157 and shares the BAY15d bayonet base. It operates at 12V with filaments rated at 21W and 5W, which differs from the 2057 and 2357NA despite those bulbs sharing the same base type.
• The 2002 Honda Odyssey front parking light uses the 1157NA, while adjacent model years use the 1034NA. Although both share the BAY15d base and natural amber glass, they carry different ANSI designations and should not be treated as direct substitutes without confirming electrical compatibility.
• The 168 bulb, specified for the 2008-2010 model years, is a miniature T10 wedge bulb rated at 4.9W and lacks the natural amber glass of the 194NA. The 194NA, used in 2005-2007, shares the T10 form factor but is rated at 3.78W and includes amber glass, making the two bulbs distinct despite their physical similarity.
• The 1995-1998 model years use the 2057, a dual-filament BAY15d bulb described as a brighter variant of the 1157, rated at 26.9W and 8W. Unlike the 1034NA and 1157NA used in later years, the 2057 does not carry the NA suffix and therefore does not feature natural amber glass.
