🔧 Outback - Headlight Bulb Replacement

You’ll be replacing the two low-beam headlight bulbs (left and right). On your Outback, the bulbs install from behind the headlight housing in the engine bay, and access is tight—so you may need to move a couple items out of the way.

Assumption: “Headlight bulbs” = the two low-beam bulbs (one per side).

Difficulty Level: Intermediate | Estimated Time: 0.5-1.5 hours

⚠️ Safety & Precautions

• ⚠️ Turn the lights OFF and let the headlight housings cool before touching bulbs (halogen bulbs get extremely hot).
• ⚠️ Do not touch the glass of the new bulb with bare fingers; skin oil can shorten bulb life. If you touch it, clean with rubbing alcohol and a lint-free towel.
• ⚠️ If you remove the battery for access, disconnect the negative terminal first and reconnect it last.
• ⚠️ Keep keys out of the ignition so no one turns the lights on while your hands are near the bulb opening.

📋 Before You Begin

• Park on level ground, shift to neutral, and set the parking brake.
• Open the hood and use a flashlight to locate the rear of each headlight housing.
• If you’ll be moving/removing the battery for access, use a 10mm socket to disconnect the negative battery terminal first. Negative off first, on last.
• Torque note: Subaru does not specify a unique torque for the bulb itself; for small clamps/hold-downs, tighten securely without stripping. Use the torque wrench only if you have the factory spec available for your hardware.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify the correct bulbs (low beams)

• Use a flashlight to look behind each headlight housing for the low-beam bulb socket (this is the main “headlight” beam).
• Confirm your replacement bulbs are H11 (Qty 2) before you start.

Step 2: Make room to reach the driver-side bulb (left side)

• If access is tight, remove the battery (common on this model).
• Use a 10mm socket and 1/4" ratchet to loosen and remove the battery terminals (negative first, then positive).
• Use a 10mm socket with a 6" extension to remove the battery hold-down hardware, then lift the battery out carefully.
• Set the battery on the ground, upright.

Step 3: Remove the driver-side low-beam bulb

• Put on nitrile gloves and safety glasses.
• Locate the low-beam electrical connector at the back of the headlight.
• Press the connector lock tab and pull the connector straight off (use needle-nose pliers gently if needed—don’t crush it).
• Twist the bulb counterclockwise to unlock it (about 1/4 turn), then pull the bulb straight out.

Step 4: Install the new driver-side low-beam bulb

• If you accidentally touch the bulb glass, clean it using rubbing alcohol (70%+) and lint-free towels, then let it dry.
• Apply a tiny smear of dielectric grease inside the electrical connector (not on the glass).
• Insert the new bulb into the housing (match the tabs), then twist clockwise to lock.
• Reconnect the electrical connector until it clicks.

Step 5: Make room to reach the passenger-side bulb (right side)

• On this model, the washer fluid filler neck can block your hand.
• Use a trim clip removal tool (or needle-nose pliers carefully) to release any clips holding the washer filler neck to the body area near the headlight.
• Move the filler neck aside just enough to reach the bulb (do not kink hoses).

Step 6: Remove and install the passenger-side low-beam bulb

• Use the same method as the driver side: unplug connector, twist bulb counterclockwise, remove.
• Install the new bulb without touching the glass, twist clockwise to lock, then reconnect the connector until it clicks.

Step 7: Reinstall what you moved (battery and/or washer neck)

• If removed, reinstall the battery and hold-down using a 10mm socket and 1/4" ratchet.
• Reconnect battery terminals using a 10mm socket: positive first, then negative last.
• If you moved the washer filler neck, re-secure it with its clips using a trim clip removal tool or needle-nose pliers.
• Torque to XX Nm (YY ft-lbs) (if you have the factory spec for your battery hold-down/terminals; otherwise tighten securely without stripping).

✅ After Repair

• Start your Outback and turn on low beams to confirm both sides light up evenly.
• Check high beams and turn signals to ensure you didn’t bump any connectors nearby.
• At night, park ~25 feet from a wall and verify both beams look even. If one looks off, the bulb may not be fully seated and locked.
