The simplest answer is: it depends on your year and trim. Most halogen Outback headlamps use H11 for low beams and 9005 (HB3) for high beams, while newer models with LED or HID systems may use different, non-replaceable modules. Always check your exact year/trim to be sure.
How to determine the right bulb for your Outback
To ensure you purchase the correct bulb, identify your vehicle’s headlight type by year and trim, then verify against your current bulb or official sources. The following guidance covers common configurations and reliable verification methods.
- Halogen headlamps (most base and mid trims on older Outbacks): Low beam typically H11; high beam typically 9005 (HB3).
- Fog lights on many trims: Commonly H11, but some packages may use a different size such as 9005 or H16 depending on the model year and equipment.
- LED or HID headlamps (common on newer or higher-end trims): Often use integrated LED modules or HID projectors; these may not have a user-replaceable bulb and may require replacement of the entire headlight assembly or a service-specific bulb module.
In summary, if your Outback uses halogen headlights, H11 low beams and 9005 high beams are the typical sizes. If you have LED or HID headlights, refer to the service manual or dealer guidance for replacement options.
Ways to verify the exact bulb size for your specific car
Use these steps to confirm the precise bulb size for your year and trim before purchasing replacements.
- Check the owner’s manual or the Subaru official parts catalog for your exact year/trim. Look up headlight bulb specifications by model and option package.
- Inspect the bulb currently installed: remove the headlight dust cap and look at the bulb base for markings such as H11, 9005, or other codes. The base type is the most direct indicator.
- Use an online bulb finder tool. Enter your vehicle’s year, model, and trim, or your VIN, to pull the exact recommended bulb sizes for low beam, high beam, and fog lights.
- Consult a dealer or certified shop if you’re unsure. Provide the VIN and the trim level to get an exact match.
Verifying with these steps helps ensure you source the correct bulb size and avoid returning improper items or installing the wrong type.
Tips for replacing bulbs safely
- Wear gloves or use a clean cloth to handle bulbs. Oils from skin can shorten bulb life.
- Disconnect the battery or remove power before changing headlight bulbs to reduce the risk of shock or short circuits.
- Allow headlight assemblies to cool before handling, and avoid touching the glass part of the new bulb.
- If replacing a high-demand HID or LED module, consult the service manual; some systems require dealer programming or alignment after replacement.
Summary
For most Subaru Outback models with halogen headlights, expect low beams to be H11 and high beams to be 9005 (HB3). LED and HID configurations may use integrated modules or non-replaceable bulbs, requiring different service steps. Always verify the exact bulb size for your year and trim through the manual, parts catalog, or a reputable bulb finder, and follow proper safety steps during replacement.
