The Toyota Paseo high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers vehicle production spanning 1992 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
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.
The 9003 operates on a 12-volt electrical system and uses a P43t base, which is a bayonet-style fitting with a 43mm collar.
The Toyota Paseo uses the 9003 bulb for both its high beam and low beam headlight functions across all model years from 1992-1998, with a single bulb type serving both roles in each headlight housing.
The 9003 is designated as an ANSI standard bulb, meaning its specifications are governed by the American National Standards Institute and apply to vehicles sold in the United States and Canada.
Because the 9003 handles both beam functions within one bulb, the headlight housing on the Paseo does not require separate bulbs for high and low beams, a design known as a composite or single-bulb headlight system.
The 9003 bulb is cross-compatible with the H4 bulb type, as both share the same P43t base and dual-filament configuration, though the 9003 designation is the ANSI-standard reference used in North American fitment guides.
