For most 2015 Impreza models with halogen headlights, the low-beam bulb is H11 and the high-beam bulb is 9005 (HB3). Fog lights typically use H11 as well. Some trims or regional variants may have different setups or factory HID headlights, which use ballast-assisted bulbs. Always verify with your owner's manual or by inspecting the headlight assembly to confirm the exact bulb type for your vehicle.
Standard halogen headlight setup
The following overview covers the typical bulb types found in the 2015 Impreza when equipped with standard halogen headlights.
- Low beam: H11
- High beam: 9005 (HB3)
- Fog lights: H11
Note: If your car has a different configuration, such as HID or LED headlights, the bulbs and replacement procedure will differ. Confirm the exact type for your specific trim and market.
How to verify the exact bulb in your car
To ensure you purchase the correct replacement, use these verification steps outlined below.
- Check the owner's manual or dealership documentation for your trim and market—the manual lists recommended bulb types.
- Inspect the back of the headlight housing for bulb markings (often stamped on the connector or the bulb itself).
- If needed, remove the headlight bulb to read the exact part number printed on the bulb’s base and cross-check with Subaru’s parts catalog.
Verifying the exact bulb type helps avoid mismatches and ensures proper fit, electrical compatibility, and optimal performance.
Variants by region or trim
Bulb configurations can vary by country, market, or optional equipment. While halogen H11 low beams and 9005 high beams are common, some higher trims or regional packages may offer HID or LED headlights, which use different bulb types and ballast systems. When in doubt, consult the owner's manual or a Subaru service technician for your specific VIN and build date.
Summary
In short, the 2015 Subaru Impreza most commonly uses H11 low beams, 9005 high beams, and H11 fog lights on models with halogen headlights. Verify against your manual or by checking the headlight housing markings if you’re unsure, especially if your vehicle has an optional HID/LED setup. Accurate bulb identification ensures easy replacement and proper light performance.
