Additional Notes

Both the 1157NA and 1034NA are ANSI-standardized dual-filament bulbs operating at 12V with a 21W/5W power rating, meaning the higher wattage filament serves the primary function while the lower wattage filament serves a secondary role such as parking or running light duty.
Both bulb types share the BAY15d bayonet base, a two-pin offset base design where the two pins are positioned at different heights to prevent incorrect installation.
The natural amber glass of both the 1157NA and 1034NA produces a yellow-tinted output directly from the bulb envelope, without relying on a colored lens to achieve the amber appearance.
The 1034NA is classified as a variant of the 1157, meaning the two types share a closely related design and electrical profile, though they are not unconditionally interchangeable across all applications.
The Toyota Echo uses the 1157NA for the 2000, 2003, and 2005 model years, and the 1034NA for the 2001-2002 and 2004 model years, indicating that the specified bulb type alternates across the production run.
Because the 1034NA is a variant rather than a direct equivalent of the 1157NA, substituting one for the other in Toyota Echo parking light sockets warrants attention to the specific year's listed fitment before any replacement.
