🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct side

• Turn the hazard lights ON briefly, then OFF.
• Walk around and confirm which front turn signal is out (left/driver or right/passenger).
• Open the hood and use a small flashlight to locate the rear of that headlamp housing.

Step 2: Locate the turn signal bulb socket

• From behind the headlamp, find the bulb socket that feeds the turn signal area of the headlight.
• Use a small flashlight to confirm you’re on the correct socket before removing anything.

Step 3: Remove the bulb socket

• Put on nitrile gloves and safety glasses.
• Grip the socket and twist it about 1/4 turn counterclockwise by hand, then pull it straight out.
• If it’s tight, wiggle gently.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new front turn signal bulb (amber) into the socket.
• If you accidentally touch the glass, wipe it with a clean, dry cloth (still wearing nitrile gloves).

Step 5: Reinstall the socket

• Insert the socket back into the headlamp housing.
• Twist clockwise about 1/4 turn by hand until it locks in place.
• Make sure the socket sits flush; a crooked socket can let moisture in.

Step 6: Repeat on the other side (recommended)

• Replace the bulb on the opposite front turn signal the same way.
• Pairs help keep brightness and color matched.

✅ After Repair

• Turn the ignition ON and test: left signal, right signal, and hazards.
• Verify the turn signal flashes at a normal speed on the dash (fast flashing can mean a bulb isn’t seated or another bulb is out).
• Check that the bulb socket is fully locked to help prevent condensation inside the headlamp.
