Additional Notes

The 9003 is an ANSI-standardized dual-filament halogen bulb rated at 12 volts with a 60W high-beam filament and a 55W low-beam filament, fitted with a P43t base. Its dual-filament design allows a single bulb to serve both beam functions within one housing.
The P43t base is a bayonet-style mount with a 43mm collar, a format that is physically distinct from single-filament bases such as H1 or H7. This base type is not interchangeable with those single-filament variants even when wattage ratings are similar.
The 9003 designation is the ANSI classification used in the United States and Canada. The same bulb is sold under the designation HB2 in other markets, and the two designations refer to the same physical and electrical specification.
The Toyota Yaris (2013-2014 and 2018) uses the 9003 bulb for the daytime running light function across those model years without noted variant distinctions.
The 2019 Toyota Yaris specifies the 9003 bulb specifically for vehicles equipped with halogen capsule headlamps, indicating that the 2019 model year included at least one additional headlamp configuration for which this bulb size does not apply.
