The Suzuki Esteem high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production years spanning 1995 to 2002.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Esteem uses the 9003 bulb for both high beam and low beam headlights across all model years from 1995-2002.
The 9003 is an ANSI-standard halogen bulb recognized in the United States and Canada, operating at 12 volts with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
Because the 9003 contains two filaments within a single housing, one bulb serves both beam functions, which is why the same part number appears in both the high beam and low beam positions on the Esteem.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm collar, which physically determines whether a given bulb is compatible with a particular headlight housing.
The 9003 is electrically and physically equivalent to the European H4 bulb type, meaning bulbs sold under either designation share the same base, voltage, and wattage ratings and are generally interchangeable.
The consistent use of the 9003 across the entire 1995-2002 production span means a single bulb specification covers all Esteem headlight replacements without variation by year.
