The Suzuki Sidekick high beam and low beam headlight bulbs both utilize a 9004 size. The replacement chart covers vehicle production spanning 1989 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Sidekick uses the 9004 bulb size across all model years from 1989-1998 for both high beam and low beam headlight positions.
The 9004 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions within one housing.
The 9004 operates on a 12-volt electrical system and draws 65 watts on the high beam filament and 45 watts on the low beam filament.
The 9004 uses a P29t base, which is a specific connector type that physically locks the bulb into the headlight assembly and is not interchangeable with other base configurations such as P43t or P22d.
The 9004 is an ANSI-standardized bulb type recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications established by the American National Standards Institute.
Because the 9004 handles both beam functions in the Suzuki Sidekick (1989-1998), a single failed bulb results in the loss of both high and low beam output on the affected side.
