📋 Before You Begin
- 🅿️ Park your Outback on level ground and set the parking brake.
- 💡 Turn the light switch OFF and make sure the hazard lights are OFF.
- 🚪 Open the rear liftgate fully.
- 🧤 Put on nitrile gloves before handling the new bulbs.
- 📌 A lamp assembly is the full rear light unit mounted to the body.
- 📌 A bulb socket is the plastic holder that twists into the lamp assembly.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the Liftgate and Find the Rear Lamp Fasteners
- Use your hands to open the rear liftgate fully.
- Use a flashlight to look at the inner edge of the rear combination lamp assembly.
- You will see two 10mm fasteners holding the lamp assembly to the body.
Step 2: Remove the Rear Lamp Fasteners
- Use a 10mm socket and ratchet handle to remove the two lamp assembly fasteners.
- Place the fasteners on a clean microfiber towel so they do not roll away.
- Do not use power tools here. The fasteners are small and can strip.
- Hand tools give better control.
Step 3: Release the Lamp Assembly from the Body
- Use both hands to hold the lamp assembly.
- Pull the lamp assembly straight rearward, away from the vehicle body.
- If it feels stuck, use a plastic trim clip removal tool at the outer edge only and apply gentle pressure.
- Do not pry with metal tools against the paint.
- The lamp has guide pins that pop out of plastic retainers.
Step 4: Identify the Rear Turn Signal Bulb Socket
- Use a flashlight to look at the back of the removed lamp assembly.
- The rear turn signal bulb socket is the socket aligned with the amber turn signal section of the lamp.
- Do not pull on the wiring harness. Hold the plastic socket body only.
Step 5: Remove the Rear Turn Signal Socket
- Use your gloved hand to grip the rear turn signal bulb socket.
- Turn the socket counterclockwise about a quarter turn.
- Pull the socket straight out of the lamp assembly.
- No torque spec applies because the bulb socket is hand-tight only.
Step 6: Remove the Old Bulb
- Use your gloved fingers to pull the old rear turn signal bulb straight out of the socket.
- If it feels tight, gently wiggle the bulb while pulling straight out.
- Do not squeeze the glass hard.
- A wedge bulb is a push-in bulb that does not screw in.
Step 7: Install the New Rear Turn Signal Bulb
- Use nitrile gloves to hold the new rear turn signal bulb.
- Push the new bulb straight into the socket until fully seated.
- Make sure the bulb is straight and secure in the socket.
- A fully seated bulb prevents flicker.
Step 8: Reinstall the Bulb Socket
- Use a flashlight to align the socket tabs with the lamp assembly opening.
- Insert the socket into the lamp assembly.
- Turn the socket clockwise about a quarter turn until it locks.
- Do not overtighten. Stop when the socket locks by hand.
Step 9: Reinstall the Rear Lamp Assembly
- Use both hands to align the guide pins with the body retainers.
- Push the lamp assembly straight forward into place until it sits flush with the body.
- Make sure the lamp gasket sits evenly and is not folded.
- The gasket is the soft seal that helps keep water out.
Step 10: Tighten the Rear Lamp Fasteners
- Use a 10mm socket and ratchet handle to install the two rear lamp fasteners.
- Tighten them evenly by hand.
- Torque to 5 Nm (44 in-lbs)
- Do not overtighten. The lamp housing can crack.
Step 11: Repeat on the Other Side
- Use the 10mm socket and ratchet handle to remove the two fasteners on the other rear lamp assembly.
- Use both hands to pull the lamp straight rearward.
- Use your gloved hand to remove the turn signal socket, replace the bulb, and reinstall the socket.
- Use the 10mm socket and ratchet handle to reinstall the lamp fasteners.
- Torque to 5 Nm (44 in-lbs)
Step 12: Test the Rear Turn Signals
- Turn the ignition ON without starting the engine if needed.
- Move the turn signal stalk down to test the left rear turn signal.
- Move the turn signal stalk up to test the right rear turn signal.
- Press the hazard switch to confirm both rear turn signals flash together.
- If one side does not flash, turn everything OFF and reseat the bulb and socket.
✅ After Repair
- ✅ Confirm both rear turn signals flash at normal speed.
- ✅ If the dash indicator blinks very fast, one bulb may be loose or the wrong type.
- ✅ Check that both lamp assemblies sit flush against the body.
- ✅ Make sure the liftgate opens and closes normally without touching the lamps.
- ✅ After the next rain or wash, check inside the lamp for moisture.
