🔧 Outback - Front Turn Signal Bulb Replacement
Your Outback’s front turn signal bulbs sit inside the headlight assemblies. Replacement is done from under the hood by twisting the bulb socket out, swapping the bulb, and reinstalling the socket so it seals properly against moisture.
Difficulty Level: Beginner | Estimated Time: 0.3-0.8 hours
⚠️ Safety & Precautions

📋 Before You Begin
- Park on level ground, shift to neutral, and set the parking brake.
- Turn the key off and remove it.
- Open the hood and have your flashlight ready so you can clearly see the bulb sockets.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm which bulb you’re replacing
- Turn the hazard lights on briefly, then off (use the dash hazard switch).
- Walk around and confirm which front corner is out.
- Open the hood again and use a flashlight to locate the turn signal socket at the back of that headlight assembly.
Step 2: Access the front turn signal socket (from under the hood)
- Stand at the back of the headlight and look for the socket that points into the headlight housing.
- Use a flashlight to confirm you’re on the turn signal socket (not the low beam/high beam socket).
- Put on nitrile gloves.
Step 3: Remove the bulb socket
- Grip the socket firmly and rotate it about 1/4 turn counterclockwise by hand.
- Pull the socket straight out of the headlight housing.
Step 4: Replace the bulb
- Pull the old bulb straight out of the socket.
- Using nitrile gloves (or a clean paper towel), push the new 7440A amber bulb straight into the socket until fully seated.
Step 5: Reinstall the socket
- Insert the socket back into the headlight housing, keeping it straight so the seal sits flat.
- Rotate the socket clockwise about 1/4 turn until it locks.
- If it feels crooked, remove and reseat.
Step 6: Test operation
- Turn the ignition to ON and activate the left/right turn signal to verify normal flash rate.
- Turn on hazard lights and confirm both front turn signals work evenly.
✅ After Repair
- Verify the turn signal flashes at a normal speed (fast flashing usually means another bulb is out).
- At night, confirm the repaired side matches the other side in brightness and color.
- If there’s any condensation later inside the headlight, recheck that the socket is fully locked and seated.
