Additional Notes

The front side marker position on the Toyota Echo alternates between two bulb sizes across model years, with 1157NA fitted to 2001, 2003, and 2005 models, while 1034NA is fitted to 2000, 2002, and 2004 models.
Both 1157NA and 1034NA are ANSI-standard dual-filament bulbs sharing the BAY15d bayonet base and natural amber glass, operating at 12V with a 21W/5W filament rating. The 1034NA is classified as a variant of the 1157NA.
Because the 1034NA is a variant of the 1157NA and both share the BAY15d base with identical voltage and wattage ratings, the physical and electrical relationship between the two is close, though they are listed as distinct part numbers across alternating model years on the Toyota Echo front side marker position.
The rear side marker position on the Toyota Echo uses two different bulb types depending on the model year, with 7443 fitted to 2000-2002 and 12961 fitted to 2003-2005.
The 7443 is an ANSI-standard dual-filament wedge bulb in the T20 form factor, rated at 12V and 21W/5W, making it a higher-output bulb relative to the single-filament 12961.
The 12961 is a Philips part number rather than an ANSI designation, identifying a miniature T10 wedge bulb with a W2.1x9.5d base, rated at 12V and 5W, with a single filament.
The front and rear side marker positions on the Toyota Echo do not share any common bulb types, as the front positions use BAY15d bayonet-base bulbs while the rear positions use wedge-base bulbs of differing sizes and filament configurations.
Substituting a dual-filament bulb such as the 7443 for a single-filament bulb such as the 12961 in the rear side marker position, or vice versa, would represent a mismatch in both form factor and filament configuration, as the T20 and T10 wedge bases are not interchangeable.
