Suzuki Grand Vitara Headlight Bulb Size

Additional Notes

• The Suzuki Grand Vitara uses three distinct halogen bulb types across its headlight specifications: the 9005, the 9003, and the H7, each governed by different international standards and carrying different electrical and physical characteristics.
• The 9005 is a single-filament halogen bulb operating at 12V and 65W, fitted with a P20d base and standardized under the ANSI specification used in the United States and Canada. It serves exclusively as the high beam bulb in the Grand Vitara for model years 2006-2013.
• The 9003 is a dual-filament halogen bulb operating at 12V with a 60W filament for high beam and a 55W filament for low beam, fitted with a P43t base. Its dual-filament design means a single bulb handles both beam functions within one housing position.
• In the Grand Vitara for model years 1999-2005, the 9003 serves as both the high beam and low beam bulb, a direct consequence of its dual-filament construction.
• The H7 is a single-filament halogen bulb operating at 12V and 55W, fitted with a PX26d base. It is standardized under the ECE regulation used in Europe and internationally, though it also carries approval for use in the United States and Japan.
• For model years 2006-2013, the low beam position uses the H7 while the high beam uses the 9005, meaning the two positions require separate, non-interchangeable bulbs with different base types and wattage ratings.
• The 9003 and H7 are not interchangeable despite both being halogen bulbs rated at 12V. The 9003 uses a P43t base and carries two filaments, while the H7 uses a PX26d base and carries one filament, making the physical connectors and housing sockets incompatible between the two types.
• The 9005 and 9003 are similarly non-interchangeable, as the 9005 uses a P20d base compared to the P43t base of the 9003, and the 9005 operates at a higher wattage of 65W versus the 60W high beam filament of the 9003.
