Subaru Impreza Headlight Bulb Size

Subaru Impreza headlight bulbs utilize 9005, 9003, H11, and D2R sizes depending on beam type and model year, with high beam applications requiring 9005 or 9003 bulbs and low beam applications requiring H11, D2R, or 9003 bulbs. The replacement chart covers vehicle production years spanning 1993 to 2019 with corresponding bulb size specifications.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The 9003 bulb is a dual-filament halogen type rated at 12V with a 60W high beam filament and a 55W low beam filament, using a P43t base. In the Subaru Impreza spanning 1993-2001, this single bulb type served both high beam and low beam functions simultaneously, which is characteristic of a dual-filament design.
The 9005 bulb is a single-filament halogen type rated at 12V, 65W, with a P20d base, conforming to the ANSI standard used in the United States and Canada. Because it carries only one filament, it is dedicated exclusively to the high beam function, unlike the 9003 it replaced in later Impreza configurations.
The H11 is a single-filament halogen bulb rated at 12V, 55W, with a PGJ19-2 base. It follows the ECE standard but holds US approval as well. In the Subaru Impreza, it appears as the low beam bulb for 2015-2019 model years specifically under halogen capsule headlamp configurations.
The D2R is a high-intensity discharge (HID) xenon bulb rated at 85V, 35W, with a P32d-3 base. It is engineered for reflector-type housings and requires an external ignitor to initiate the arc discharge that produces light. It is not interchangeable with halogen bulb types due to its fundamentally different operating voltage and ignition requirements.
For the 2015-2016 Subaru Impreza, the low beam position has two distinct fitments depending on headlamp type: H11 for halogen capsule headlamps and D2R for HID headlamps. These two configurations are not interchangeable, as the HID system operates at a significantly higher voltage and relies on different housing optics.
The 2017-2019 Subaru Impreza specifies both the 9005 high beam and H11 low beam exclusively under the halogen capsule headlamp condition, indicating that non-halogen headlamp variants in those years use a different bulb arrangement not covered by these specifications.
The 9003 and 9005 bulbs share the same ANSI regulatory framework but differ in base type, filament count, and wattage. The P43t base of the 9003 and the P20d base of the 9005 are physically incompatible, making direct substitution between the two impossible without modification.
The transition from the 9003 in the 1993-2001 Subaru Impreza to separate 9005 and H11 bulbs in the 2015-2019 range reflects a shift from a combined dual-filament design to a split-function system where dedicated bulbs handle each beam independently.
