🔧 Traverse - Front Turn Signal Bulb Replacement

On your Traverse, the front turn signal is inside the headlamp assembly. Most LS models use a replaceable amber bulb, accessed from behind the headlamp (usually through the front wheel-well liner).

📋 Before You Begin

• Turn the steering wheel fully away from the side you’re working on (gives more room).
• Set the parking brake and place wheel chocks behind the rear tires.
• If you’re doing both sides, plan to do one side at a time so you don’t mix up clips.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm you have a replaceable bulb

• Turn the turn signal on briefly, then turn the ignition OFF.
• Use a flashlight to look behind the headlamp from the wheel-well area.
• If you find a twist-out plastic socket with wires going to it, you have a replaceable bulb.
• If there is no bulb socket and the lamp is a sealed LED unit, skip to Step 8.

Step 2: Open access at the front wheel-well liner

• Wear safety glasses and nitrile gloves.
• Use a 7mm socket with a 1/4" ratchet and extension to remove the small screws along the front edge of the wheel-well liner.
• Use a trim clip removal tool to pop out any plastic push clips in the same area.
• Pull the liner back just enough to reach behind the headlamp. Don’t crease the liner.

Step 3: Locate the front turn signal bulb socket

• Use a flashlight to find the socket going into the headlamp near the turn signal area.
• Grasp the socket body (not the wires).

Step 4: Remove the bulb socket

• Twist the socket counterclockwise about a quarter-turn, then pull it straight out.
• If it feels stuck, wiggle gently while pulling—do not force the wiring.

Step 5: Remove the old bulb

• Pull the bulb straight out of the socket.
• Check the bulb number printed on the base—use that to match the correct replacement.

Step 6: Install the new bulb

• Put on nitrile gloves (prevents skin oil on the bulb).
• Push the new bulb straight into the socket until fully seated.

Step 7: Reinstall socket and close up the liner

• Insert the socket into the headlamp and twist clockwise to lock.
• Reposition the wheel-well liner.
• Reinstall screws using a 7mm socket and reinstall push clips using a trim clip removal tool (press clips in by hand).

Step 8: If your Traverse has a sealed LED front turn signal (no bulb)

• If there is no removable bulb/socket, the turn signal is part of the headlamp assembly (LED). The usual fix is replacing the headlamp assembly, not a bulb.
• Before buying parts, confirm by checking for a twist-out socket from behind the headlamp using a flashlight.
• If you want, tell me whether you see a twist-out socket or a sealed housing and I’ll give you the exact headlamp replacement steps.

✅ After Repair

• Turn the ignition ON and test the left and right turn signals.
• Verify the turn signal flashes normally (a fast flash usually means a bulb isn’t working).
• Make sure the wheel-well liner is secured so it won’t rub the tire.
