How to Replace the LED Headlight Assembly on a 2020 Subaru Outback (Both Sides) (Trim: Base | Body: Wagon)
Step-by-step bumper cover removal, tools/parts list, wiring checks, and torque specs for a proper fix for 2020
🔧 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.

đź“‹ 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.
âś… 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.
