The Isuzu Hombre uses a 9005 bulb size for high beam headlights and a 9006 bulb size for low beam headlights. The replacement chart covers vehicle production years from 1996 to 2000 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 Isuzu Hombre uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across all model years from 1996-2000.
Both the 9005 and 9006 are ANSI-standardized halogen bulbs rated for 12V systems, making them compatible with the North American electrical standard used in passenger vehicles of that era.
The 9005 is a single-filament halogen bulb operating at 65W, fitted with a P20d base, and is dedicated solely to the high beam function.
The 9006 is a single-filament halogen bulb operating at 55W, fitted with a P22d base, and handles the low beam function exclusively.
Although the 9005 and 9006 share a similar physical profile, their bases differ: the P20d base on the 9005 and the P22d base on the 9006 are not interchangeable, preventing accidental cross-installation between the two positions.
The wattage difference between the two bulbs, 65W for the high beam and 55W for the low beam, reflects the greater light output required for high beam operation compared to the more controlled projection of the low beam.
Both bulb types carry ANSI certification applicable to the United States and Canada, indicating they conform to a defined performance and dimensional standard rather than a manufacturer-specific specification.
