Yes. On most 2015 Outback models with halogen headlights, you can replace a burned-out bulb yourself by swapping the bulb behind the headlight housing, usually in about 15–30 minutes. If your Outback uses HID or LED headlights, the replacement routine is more involved and may require a professional.
Identify bulb type and prepare
Before you begin, confirm whether you have halogen, HID, or LED headlights and which bulb types your model uses. The majority of Outbacks from this year use halogen bulbs in the low-beam position and the high-beam bulb is often a separate type. Fog lights, when present, may use the same or different bulbs. Check the owner’s manual or inspect the back of the headlight to confirm exact type. Gather the right replacement bulb and safety gear first.
Tools and materials you'll need:
- Replacement bulb of the correct type (for example H11 for low beam, 9005 for high beam)
- Clean gloves or a microfiber cloth to handle the bulb (avoid touching the glass with bare skin)
- Flathead screwdriver or coin (optional, to assist with the dust cap if tight)
- Flashlight and camera or notes to remember wiring orientation
- If you're replacing a fog light bulb, additional bulbs may be needed
With the bulb type verified and supplies ready, proceed to access the headlight assembly.
Accessing and removing the old bulb (halogen low-beam)
The following steps guide you through removing the halogen low-beam bulb from the Outback’s headlight housing.
- Park the car on a level surface, turn off the engine, and remove the key. Set the parking brake for safety.
- Open the hood and locate the back of the headlight housing. Remove the rubber dust cap by turning it counterclockwise and pulling it off to expose the bulb and connector.
- Disconnect the electrical connector from the bulb by pressing the release tab and pulling the connector away from the bulb.
- Remove the bulb’s retaining mechanism: this is usually a small plastic clip or a metal ring. Gently unclip or rotate to free the bulb.
- Carefully remove the old bulb from the housing. Try not to touch the glass; if you did, wipe it with alcohol and a lint-free cloth or replace the bulb.
- Install the new bulb by inserting it into the housing and aligning the tabs. Secure the bulb with the retaining clip or ring, then rotate until locked.
- Reconnect the electrical connector to the bulb and ensure it clicks into place. Refit the rubber dust cap, turning it clockwise to seal the housing.
- Test the new bulb by turning on the headlights. If it works, reassemble any components you may have moved and close the hood.
If the bulb doesn’t light, double-check the connector, fuse, and alignment. In some cases you may need to remove and reseat the bulb to ensure proper contact.
What about HID or LED headlights?
HID or LED configurations
HID (high-intensity discharge) or LED headlight systems in the 2015 Outback are often not designed for field replacement of individual bulbs. If your vehicle has HID or LED low beams, you may need a dealer or automotive technician to replace the bulb, ballast, or LED module. Some configurations allow bulb replacement, but you’ll typically face higher costs and special alignment requirements. Always check the owner’s manual and VIN-specific guidance.
If you do replace an HID bulb, handle the bulb with gloves and avoid touching the glass; ensure the ballast is reconnected correctly. LED headlight modules usually require a full headlight assembly replacement if the LED fails.
Testing, alignment, and safety tips
After replacement, test the lights in a dark area to confirm proper operation and check beam alignment. If your headlights seem misaligned, consult the service manual for calibration steps or arrange a professional alignment. Misaligned headlights can reduce visibility and blind oncoming drivers, so ensure proper aim.
Dispose of the old bulb properly and keep spare bulbs on hand for future maintenance.
Summary
Replacing a headlight bulb on a 2015 Subaru Outback is usually a straightforward DIY task when dealing with halogen headlights. Confirm the bulb type, gather the correct replacement, and follow the safe steps to remove and install the new bulb. For HID or LED configurations, seek professional assistance to avoid damage or misalignment. With the right approach, you can restore your vehicle’s visibility quickly and safely.
