Toyota Matrix Turn Signal Bulb Size

The Toyota Matrix front turn signal requires 3357NA, 3457NA, or 1034NA bulb sizes, while the rear turn signal uses a 7440NA bulb size. The replacement chart covers 2003 through 2013 production years with corresponding bulb size specifications.

Additional Notes

The Toyota Matrix rear turn signal position uses the 7440NA bulb across all model years from 2003-2013, making it the only position in these specifications with no variation across the entire production run covered.
The 7440NA is a single-filament T20 wedge bulb rated at 12V and 21W. Its natural amber glass produces the required amber signal color without relying on a colored lens or painted coating.
The front turn signal position on the Toyota Matrix changed bulb types multiple times across model years. The 1157NA was used in 2003, 2006, and 2007; the 1034NA appeared in 2004, 2005, and 2008; the 3457NA covered 2009-2012; and the 3357NA was introduced for 2013.
The 1157NA and 1034NA share the same BAY15d bayonet base and are both dual-filament bulbs rated at 12V. However, their wattage ratings differ slightly, with the 1157NA rated at 21W/5W and the 1034NA rated at 21/5W, and they are listed as distinct part numbers under ANSI standards.
The 3457NA, used in the front turn signal position for 2009-2012, is a dual-filament T25 wedge bulb rated at 12V with a 27W/7W output. Its wedge base design is physically incompatible with the BAY15d bayonet socket used by the 1157NA and 1034NA in earlier model years.
The 3357NA, specified for the 2013 front turn signal, shares the T25 wedge form and 12V/27W rating with the 3457NA but is a single-filament bulb rather than a dual-filament one. Substituting a dual-filament 3457NA in a socket wired for a single-filament application can result in incorrect circuit behavior.
The shift from BAY15d bayonet-base bulbs in earlier Matrix model years to T25 wedge-base bulbs starting in 2009 represents a socket-level change at the front turn signal position, meaning bulbs from the two groups are not interchangeable regardless of wattage similarity.
All bulb types listed across both turn signal positions carry the "NA" suffix, indicating natural amber glass construction. This designation conforms to ANSI standards applicable in both the United States and Canada.
