🔧 Outback - Headlight “Bulb” Replacement (Factory LED)

On your Outback, the headlights are factory LED units, so there aren’t serviceable “bulbs” you can swap from the back. If a headlight is out, the typical fix is replacing the complete headlamp assembly on that side (or repairing wiring/connector if that’s the cause).

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours


⚠️ Safety & Precautions

  • ⚠️ Let the front end cool before working near radiators/condensers.
  • ⚠️ Disconnect the negative battery cable before unplugging headlamp connectors to reduce short-circuit risk.
  • ⚠️ Support the bumper cover so it doesn’t scratch paint or strain wiring.

🔧 Required Tools

You'll need the following tools for this repair:

  • 10mm socket
  • 1/4" ratchet
  • 6" extension (1/4")
  • Trim clip removal tool
  • Panel clip pliers
  • Phillips #2 screwdriver
  • Flat-blade trim screwdriver
  • Torque wrench (inch-pound or small Nm range)
  • Fender cover
  • Nitrile gloves
  • Safety glasses

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Left headlamp assembly (LED) - Qty: 1
  • Right headlamp assembly (LED) - Qty: 1
  • Front bumper cover retainer clips - Qty: 1 set

📋 Before You Begin

  • Park on level ground, shift to Park, and set the parking brake.
  • Turn the headlight switch OFF and remove the key/fob from the vehicle area.
  • Open the hood and install a fender cover to protect paint.
  • Disconnect the battery: use a 10mm socket to remove the negative terminal and isolate it so it can’t spring back.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which headlamp assembly is failed

  • Turn the lights ON and verify which side is out (left/right). Then turn lights OFF.
  • If both are out, check fuses first.

Step 2: Remove the upper bumper cover fasteners

  • Open the hood.
  • Use a trim clip removal tool and panel clip pliers to remove the plastic push-clips along the top edge of the bumper cover.
  • Use a Phillips #2 screwdriver to remove any upper screws (if equipped).

Step 3: Release the bumper cover at the fender corners

  • At each front wheel opening, use a trim clip removal tool to remove the fasteners securing the bumper cover edge to the fender liner.
  • Gently pull the bumper cover corner straight outward to release the side retainers.
  • Pull outward—don’t “peel” it forward.

Step 4: Remove the lower bumper cover fasteners

  • From underneath, use a trim clip removal tool to remove the lower push-clips.
  • If there are small bolts, remove them with a 10mm socket and 1/4" ratchet.

Step 5: Move the bumper cover forward for access

  • With a helper supporting the cover, pull the bumper cover forward enough to access the headlamp area.
  • If you have any electrical connectors on the bumper cover, unplug them by pressing the lock tab and pulling straight out (use a flat-blade trim screwdriver only if needed to gently lift the lock).
  • Never pull on the wires—pull the connector body.

Step 6: Unbolt the headlamp assembly

  • Remove the headlamp mounting bolts using a 10mm socket, extension, and 1/4" ratchet.
  • Carefully slide the headlamp assembly forward to release alignment pins.
  • Unplug the headlamp electrical connector (press the lock tab, pull straight off).

Step 7: Install the new headlamp assembly

  • Plug in the headlamp connector until it clicks.
  • Set the headlamp into place, aligning the locating pins.
  • Install the mounting bolts by hand first to avoid cross-threading, then tighten with a 10mm socket.
  • Torque to 7.5 Nm (66 in-lbs) using a torque wrench.

Step 8: Reinstall the bumper cover

  • Position the bumper cover and snap the sides back into the fender retainers.
  • Reinstall lower fasteners using a trim clip removal tool and 10mm socket (if equipped).
  • Reinstall wheel-opening fasteners using a trim clip removal tool.
  • Reinstall upper fasteners using a trim clip removal tool and Phillips #2 screwdriver.

Step 9: Reconnect the battery and function test

  • Reconnect the negative battery terminal using a 10mm socket.
  • Torque to 5.4 Nm (48 in-lbs) using a torque wrench.
  • Turn headlights ON and verify left/right low beam operation and turn signals.

✅ After Repair

  • Check the panel gaps around the headlamp and bumper cover—everything should sit even.
  • At night, verify beam aim looks even side-to-side; adjust only if needed using the headlamp aiming adjuster (turn with a Phillips #2 screwdriver).
  • Recheck for warning lights on the dash after a short test drive.
