What size bulb for Subaru Impreza headlight?

There isn’t a single universal bulb size for the Subaru Impreza headlight; it depends on the model year and trim. In many recent models, the common halogen low-beam bulb is typically H11 and the high-beam bulb is 9005, but you should confirm the exact size for your car.

What determines the bulb size

The headlight system in the Impreza has evolved across generations. Different generations and trims may use different bulb types for low beams, high beams, and fog lights. To ensure you buy the correct bulb, verify against your specific vehicle’s documentation or by inspecting the bulb itself.

Common configurations you might encounter

These examples reflect what some Subaru Impreza models have used in practice. Always check your own car to be certain, as there are exceptions by year and trim.

• Low beam bulb size: commonly H11 on many recent Imprezas.


• High beam bulb size: commonly 9005 (HB3) on many recent Imprezas.


• Fog light bulb size: varies by generation and trim; common options include H11 or H16.

Using this quick reference can help you narrow down your options, but it should not replace a model-specific check. If your Impreza uses HID or LED headlights, the bulb replacement process and part numbers will differ, and not all headlight units have replaceable bulbs.

How to verify your exact bulb size

• Check the owner's manual: look for a section on replacing headlight bulbs, which lists the exact bulb type for your year and trim.


• Inspect the bulb in the headlight housing: the base type (for example, H11, 9005, H7, etc.) is usually stamped on the metal base or printed on the bulb sleeve.


• Use an online parts finder: enter your exact year, model, and trim on Subaru’s official parts site or a reputable auto parts retailer to pull the correct bulb size.


• Ask a pro or visit a dealership: if you’re unsure, a technician can confirm the correct bulb size and replacement procedure for your specific vehicle.

Confirming with one of these methods will help you avoid ordering the wrong bulb and ensure proper fit and performance.

Tips for replacement and handling

Handle halogen bulbs with care: use gloves or a clean cloth to avoid oils from your skin contacting the glass, which can shorten bulb life. If your Impreza uses HID or LED headlights, bulbs may not be replaceable in the same way, and you might need a whole headlight assembly or ballast module.

Summary

In short, the headlight bulb size for an Impreza is not universal and depends on the model year and trim. For many recent models, anticipate H11 for low beams and 9005 for high beams, with fog light sizes varying by trim. Always verify with the owner’s manual, inspect the existing bulb, or use a trusted parts finder to confirm the exact type for your vehicle. When in doubt, consult a professional to ensure correct fit and safe operation.

Do I need H11 or 9005?

H11 bulbs are designed for use as low beam headlights, while 9005 bulbs are typically used for high beams. This results in a higher brightness level for the 9005 bulbs compared to the H11 bulbs.

Are H11 and 9005 the same bulb?

Difference between these bulbs will be the O-ring on the base. H11 on the left side will have a big pronounced O-ring on the base of the bulb versus the 9005.
