Additional Notes

The Hyundai Scoupe uses two different tail light bulb sizes across its 1991-1995 model years: the 1157 for 1991-1992 and the 2357 for 1993-1995.
Both the 1157 and 2357 are ANSI-standardized dual-filament bulbs recognized in the United States and Canada, each serving separate brightness levels within the same tail light assembly.
Both bulb types share the BAY15d bayonet base, a double-contact offset-pin base that physically locks the bulb into position and ensures correct polarity alignment.
The dual-filament design in both types allows a single bulb to handle two functions, typically running light and brake or turn signal operation, through independent filaments operating at different wattages.
The 1157 operates at 12V with filaments rated at 21W and 5W, while the 2357 operates at 12V with filaments rated at 26.9W and 8W, making the 2357 the higher-output variant of the two.
Although the 1157 and 2357 share the same BAY15d base and are physically interchangeable in many housings, the Hyundai Scoupe (1993-1995) is specified for the 2357, which draws more wattage than the 1157 used in 1991-1992 models.
The higher wattage of the 2357 produces greater luminous output than the 1157, a factor relevant to tail light visibility performance in the 1993-1995 Scoupe.
