The Hyundai Scoupe brake light utilizes 1157 and 2357 bulb sizes depending on the specific version of the vehicle. Data for the provided components covers the range from 1991 to 1995.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hyundai Scoupe brake light position uses the 2357 bulb for 1993-1995 and the 1157 bulb for 1991-1992. Both are dual-filament bulbs sharing the BAY15d bayonet base, which means the socket type is physically compatible across all five model years, though the bulbs themselves are not direct equivalents in output.
The 2357 and 1157 are both ANSI-standard dual-filament bulbs rated at 12V, but they differ in wattage. The 2357 draws 26.9W on its high filament and 8W on its low filament, while the 1157 draws 21W and 5W respectively. The 2357 is the higher-output variant of the two.
The center high mount stop light on the Hyundai Scoupe uses three different bulb types across its production run, none of which share a base type with each other. The 1991 model uses the 1073, the 1992 model uses the P21W, and the 1993-1995 models use the 921.
The 921 is a wedge-type bulb (T15 form factor) rated at 12V and 16W. Its wedge base is physically distinct from the bayonet bases found on the other bulbs listed in these specifications, making it non-interchangeable with the 1073 or P21W without a socket adapter.
The P21W follows the ECE standard used in European and worldwide markets, while all other bulbs in these specifications follow the ANSI standard used in the United States and Canada. The P21W uses a BA15s single-contact bayonet base and is rated at 12V and 21W.
The 1073 is a single-filament ANSI bulb with a BA15s bayonet base, rated at 12V and 13W. It is a lower-wattage variant of the 1156 bulb family. Its BA15s base is the same base type as the P21W, though the two bulbs belong to different international standards and differ in wattage output.
