Toyota Echo Turn Signal Bulb Size

The Toyota Echo front turn signal requires 1157NA or 1034NA bulb size, while the rear turn signal uses 7440 or 7440NA bulb size. The replacement chart covers 2000 to 2005 model years with corresponding bulb size specifications for each signal location.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The front turn signal positions across the Toyota Echo's production run use two bulb types: the 1157NA and the 1034NA. Both are dual-filament bulbs with a BAY15d bayonet base, rated at 12V with a 21W high filament and a 5W low filament, and both feature natural amber glass. The 1034NA is classified as a variant of the 1157NA.
The 1157NA appears in the Toyota Echo front turn signal position for the 2001 and 2003-2005 model years, while the 1034NA is specified for the 2000 and 2002 model years. These two bulbs share the same base type and wattage ratings but are not the same part number, and the variant relationship between them does not guarantee interchangeability without verification.
The rear turn signal position uses bulbs from the T20 wedge family throughout the full production run. The T20 wedge format uses a plastic wedge base rather than a bayonet fitting, which makes it physically incompatible with the BAY15d base found in the front position bulbs.
The 7440NA, specified for the rear turn signal on the Toyota Echo for the 2000-2002 model years, is a single-filament T20 wedge bulb rated at 12V and 21W with natural amber glass. The 7440, used in the 2003-2005 rear position, shares the same electrical ratings and T20 wedge base but has a clear rather than amber envelope.
The "NA" suffix present on the 1157NA, 1034NA, and 7440NA designations indicates natural amber glass, meaning the amber color is produced by the glass itself rather than by a coating or the housing. This is a relevant distinction in applications where housing color and light output color interact.
All four bulb types listed are ANSI standard parts applicable to both the United States and Canada, indicating they conform to a shared North American specification rather than a region-specific standard.
The single-filament construction of the 7440 and 7440NA means these rear bulbs serve only one electrical function, unlike the dual-filament front bulbs, which can serve two functions such as turn signaling and parking light operation from a single housing.
The shift from 7440NA to 7440 in the rear turn signal position between the 2002 and 2003 model years represents a change in glass tint specification while retaining the same base type, filament count, voltage, and wattage.
