⚠️ Safety & Precautions

• 🧤 Turn the lights OFF and let the headlamp area cool before reaching behind it.
• 🧯 Do not touch the glass of a halogen bulb with bare fingers; oils can shorten bulb life.
• 🔌 No battery disconnect is required, but keep the key OFF to avoid shorting anything.

📋 Before You Begin

• 🧱 Place wheel chocks behind the rear tires.
• 🔦 Open the hood and use a flashlight to locate the bulb sockets at the back of each headlamp.
• 📝 If you’re unsure which bulb to buy: remove the old bulb first and read the bulb number printed on its base (common formats look like “7440”).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct socket (turn signal)

• Open the hood and look behind the headlamp assembly using a flashlight.
• Identify the turn signal socket (it’s the socket that feeds the amber turn signal function).
• If unsure, turn hazards on briefly. Then switch them OFF before removing anything.

Step 2: Remove the turn signal bulb socket

• Reach behind the headlamp and grasp the socket firmly (use nitrile gloves for grip).
• Twist the socket counterclockwise about a quarter-turn and pull it straight out.

Step 3: Remove the old bulb

• Pull the bulb straight out of the socket (no twisting on most wedge-style bulbs).
• Check the bulb number stamped on the base and match your replacement.

Step 4: Install the new bulb

• With nitrile gloves on, press the new bulb straight into the socket until fully seated.
• If the bulb is halogen glass, avoid touching the glass. If you accidentally touch it, wipe it clean and dry before installing.

Step 5: Reinstall the socket

• Insert the socket back into the headlamp housing.
• Twist clockwise until it locks snugly by hand (no tools needed).

Step 6: If access is too tight, use the wheel-well access path (alternate method)

• Chock wheels, then raise 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 to remove the plastic clips holding the front fender liner edge.
• If needed, remove small fasteners with a 10mm socket, 1/4" ratchet, and 3" extension.
• Pull the liner back just enough to reach the rear of the headlamp, then repeat Steps 2–5.
• Reinstall liner clips/fasteners securely by hand.

Step 7: Repeat on the other side

• Replace the other front turn signal bulb the same way (best practice is to replace in pairs).

✅ After Repair

• 🔁 Turn the ignition ON and test left and right turn signals, plus hazard flashers.
• 👀 Walk around and confirm the front turn signals blink normally (not fast).
• 🧩 If you used the wheel-well method, recheck that all liner clips are fully seated.
