The Chevrolet Corsica headlight bulb size chart specifies high beam and low beam bulb sizes of 9005, 9003, and 9006 for this vehicle model. The replacement chart contains data covering 1987 to 1996 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 9005 bulb is a single-filament halogen type rated at 12V and 65W, fitted with a P20d base. It serves as the high beam headlight bulb across the full 1987-1996 production range of the Chevrolet Corsica under standard configuration.
The 9006 bulb is a single-filament halogen type rated at 12V and 55W, fitted with a P22d base. It fills the low beam position across the same 1987-1996 range under standard configuration, drawing 10W less than the 9005 used in the high beam position.
The 9003 is a dual-filament halogen bulb rated at 12V with a 60W/55W output split between its two filaments, and it uses a P43t base. Because it carries both filaments in a single housing, it handles both high and low beam functions simultaneously.
The P43t base of the 9003 differs physically from both the P20d base of the 9005 and the P22d base of the 9006, meaning the three bulb types are not interchangeable despite sharing the same 12V operating voltage.
For 1995-1996 Corsica vehicles equipped with headlamps marked "E," indicating compliance with Right Hand Rule of the Road standards, the 9003 replaces both the 9005 high beam and 9006 low beam bulbs with a single dual-filament unit per headlamp assembly.
All three bulb types, the 9005, 9006, and 9003, conform to ANSI standards applicable in the United States and Canada.
