🔧 Outback - Front Turn Signal Bulb Replacement
Your Outback’s front turn signal bulb sits in the back of the headlight housing. You’ll remove the bulb socket, swap the bulb, then test the signal before locking everything back in.
Difficulty Level: Beginner | Estimated Time: 0.3-0.8 hours
⚠️ Safety & Precautions
- Turn ignition OFF and remove the key before working around the headlight wiring.
- Let the headlight area cool first if the lights were recently on.
- Do not touch the new bulb’s glass with bare fingers; skin oils can shorten bulb life.
- If you choose the wheel-well access method, support the vehicle with jack stands—never rely on a jack alone.

You'll need the following tools for this repair:
- Safety glasses
- Nitrile gloves
- Flashlight

📋 Before You Begin
- Park on level ground, set the parking brake, and turn the headlights OFF.
- Open the hood and have your flashlight ready.
- If access is too tight from under the hood, plan to use the wheel-well method (remove the front wheel and peel back the liner).
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm which side bulb you’re replacing
- Turn on the hazard lights and walk around the Outback.
- Use your flashlight to confirm which front turn signal is out.
- Turn hazards OFF before continuing.
Step 2: Try the under-hood access (quick method)
- Put on nitrile gloves and safety glasses.
- From behind the headlight, feel for the turn signal bulb socket (it’s a twist-lock socket).
- Twist the socket counterclockwise about 1/4 turn by hand, then pull it straight out.
- Twist the socket, not the wires.
Step 3: If it’s too tight, use the wheel-well access method
- Place wheel chocks behind the rear wheels.
- Loosen the front wheel lug nuts 1/2 turn using a 19mm socket and 1/2" drive breaker bar.
- Lift the front corner with a floor jack (rated 3-ton minimum) and support it with jack stands (rated 3-ton minimum).
- Remove the wheel with the 19mm socket.
- Remove the front section of the fender liner clips using a trim clip removal tool (and a Phillips screwdriver if needed), then peel the liner back.
- Reach the back of the headlight and remove the turn signal socket by twisting counterclockwise by hand about 1/4 turn.
Step 4: Remove the old bulb
- Pull the bulb straight out of the socket by hand (it’s a wedge-style bulb).
- Compare the old bulb to the new one to confirm the same base style.
Step 5: Install the new bulb
- Install the new 7440A amber bulb by pushing it straight into the socket until fully seated.
- Keep the bulb glass clean; use nitrile gloves while handling it.
Step 6: Reinstall the socket and test
- Insert the socket back into the headlight housing.
- Twist clockwise by hand until it locks in place.
- Turn the hazard lights ON to confirm the bulb flashes normally.
Step 7: Reassemble (wheel-well method only)
- Reposition the fender liner and reinstall the clips using the trim clip removal tool (and Phillips screwdriver if equipped).
- Reinstall the wheel and snug the lug nuts with the 19mm socket.
- Lower the vehicle, then tighten lug nuts in a star pattern using the 1/2" drive torque wrench: Torque to 120 Nm (89 ft-lbs).
✅ After Repair
- Verify left and right turn signals, hazards, and the dash indicator all flash at a normal speed.
- If it “hyper-flashes” (fast blinking), recheck that the bulb is fully seated and the socket is fully locked.
- Make sure the fender liner is secured so it can’t rub the tire (wheel-well method).
