Hyundai Scoupe headlight bulbs utilize 9005, 9004, and 9006 sizes depending on beam configuration and model variation. The replacement chart covers 1991 through 1995 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hyundai Scoupe uses three distinct halogen bulb types across its headlight system: the 9005, 9006, and 9004, all of which conform to ANSI standards recognized in the United States and Canada.
The 9004 is a dual-filament halogen bulb rated at 12V with a 65W/45W output and a P29t base, meaning a single bulb serves both high and low beam functions within one housing.
The 9005 is a single-filament halogen bulb rated at 12V, 65W, with a P20d base, dedicated exclusively to high beam operation.
The 9006 is a single-filament halogen bulb rated at 12V, 55W, with a P22d base, dedicated exclusively to low beam operation.
The Hyundai Scoupe transitioned from a single-bulb system to a separate high and low beam configuration between the 1992 and 1993 model years, with the 9004 used for both beams in 1991-1992 and distinct 9005 and 9006 bulbs introduced from 1993-1995.
Because the P29t, P20d, and P22d bases are physically different from one another, the 9004, 9005, and 9006 bulbs are not interchangeable despite sharing the same 12V operating voltage.
On 1991-1992 models, the 9004 dual-filament bulb operates at 65W on high beam and 45W on low beam, reflecting the lower wattage demand of low beam illumination within a single unit.
The shift to separate 9005 and 9006 bulbs in 1993-1995 means the high beam operates at 65W and the low beam at 55W, with each function handled by an independent single-filament bulb rather than a shared dual-filament unit.
