The Isuzu Rodeo Sport high beam and low beam headlight bulbs both utilize a 9003 bulb size for optimal illumination. The replacement chart covers vehicle production spanning 2001 to 2003 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole bulb type listed across all headlight positions in the Isuzu Rodeo Sport specifications, covering model years 2001-2003.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
Because the 9003 carries both filaments within one housing, the Isuzu Rodeo Sport uses the same bulb size for both its high beam and low beam headlight positions across all listed years.
The 9003 operates on a 12V electrical system, which is standard for passenger vehicles of this type.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm cap width, which physically determines socket compatibility and is not interchangeable with other base types.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is functionally equivalent to the European H4 bulb, though the two designations reflect different regional certification systems and may carry minor regulatory distinctions depending on the market.
