đź”§ Outback - Front Turn Signal Bulb Replacement
Your front turn signal bulbs sit inside the headlight housings. Replacing them is a simple job: you’ll access the bulb socket from behind the headlight, twist it out, swap the bulb, and test the signals.
Difficulty Level: Beginner | Estimated Time: 0.3-0.7 hours
⚠️ Safety & Precautions
- ⚠️ Turn the ignition OFF and remove the key before starting.
- ⚠️ Let the headlight area cool down if lights were recently on.
- ⚠️ Wear gloves and do not touch the new bulb glass with bare fingers (skin oils can shorten bulb life).
- ⚠️ If you raise the front for access, 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

- Phillips screwdriver #2

- Fender liner push clips - Qty: 4
đź“‹ Before You Begin
- Park on level ground and set the parking brake.
- Turn the steering wheel to full lock (left or right) for more room at the front of the wheel well.
- If your hands don’t fit comfortably, plan to loosen the front wheel-well liner (it’s the plastic splash shield).
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Set up for access
- Open the hood and use a flashlight to look behind the headlight on the side you’re replacing.
- If you can reach the bulb socket by hand, you can skip to Step 3.
- If it’s too tight, continue to Step 2 to loosen the wheel-well liner.
Step 2: Loosen the front wheel-well liner (if needed)
- Place wheel chocks behind the rear wheels.
- Lift the front corner with a floor jack (rated 3-ton minimum) and support it with jack stands (rated 3-ton minimum).
- Use a trim clip removal tool and flat trim pry tool to remove the plastic push-clips along the front edge of the liner.
- If equipped with screws, remove them using a Phillips screwdriver #2.
- Peel the liner back just enough to reach behind the headlight. Only bend it; don’t crease it.
Step 3: Remove the turn signal bulb socket
- From behind the headlight, locate the turn signal socket (the socket that feeds the amber turn signal bulb).
- Grip the socket firmly and rotate it counterclockwise about 1/4 turn by hand (use nitrile gloves for grip), then pull it straight out.
Step 4: Replace the bulb
- Pull the old bulb straight out of the socket (it’s a wedge-style bulb).
- Install the new Front turn signal bulb (amber, 7440A) by pushing it straight into the socket until fully seated.
- Do not touch the bulb glass—use nitrile gloves.
Step 5: Reinstall the socket
- Insert the socket back into the headlight housing.
- Rotate clockwise about 1/4 turn until it locks in place.
Step 6: Reassemble the wheel-well liner (if removed)
- Reposition the liner.
- Reinstall push-clips using your hands (use the trim clip removal tool to align holes if needed).
- If removed, reinstall screws using a Phillips screwdriver #2.
- Remove the jack stands (rated 3-ton minimum) and lower the vehicle using the floor jack (rated 3-ton minimum).
Step 7: Test operation
- Turn the ignition to ON and test left and right turn signals.
- Verify the turn signal flashes at a normal speed on the dash and outside.
âś… After Repair
- Confirm both front turn signals flash evenly (no “fast flash”).
- If it still “fast flashes,” recheck that the bulb is fully seated and the socket is locked.
- Make sure the wheel-well liner is secure so it doesn’t rub the tire.
