📋 Before You Begin
- Park on level ground and set the parking brake.
- Turn the headlight switch off.
- Open the hood and make sure you have room to work behind the headlamp.
- Work on one side at a time.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Access the rear of the headlamp
- Open the hood.
- Use a trim panel tool if any plastic covers or retainers block access near the headlamp.
- On the side you are servicing, find the turn signal bulb socket on the back of the headlamp assembly.
Step 2: Remove the bulb socket
- Use your hand to twist the bulb socket counterclockwise and remove it from the headlamp.
- If space is tight, use a 10mm socket, 1/4-inch ratchet, and extension bar to remove any small access bracket or duct blocking the area.
- Do not pull on the wiring.
Step 3: Replace the bulb
- Pull the old bulb straight out of the socket.
- Push the new front turn signal bulb into the socket until fully seated.
- If the bulb is glass halogen, wear gloves and keep the glass clean.
Step 4: Reinstall the socket
- Align the socket tabs with the headlamp housing.
- Twist the socket clockwise until it locks in place.
- Make sure the socket is fully seated so moisture cannot enter.
Step 5: Test the new bulb
- Turn on the ignition.
- Activate the turn signal for that side and confirm it flashes normally.
- If it does not light, remove the socket and check bulb seating and connector contact.
✅ After Repair
- Check both front turn signals to make sure they flash at the same rate.
- Verify the dash indicator is not hyper-flashing.
- If the bulb still does not work, inspect the fuse and socket contacts.
