⚠️ Safety & Precautions

• 🛑 Work on level ground and use jack stands if a wheel comes off the ground.
• 🧤 Let the headlamp area cool first; bulbs and housings can get hot.
• ⚡ Keep the ignition OFF while unplugging/plugging bulb sockets.
• 🔍 Don’t touch a halogen bulb glass with bare fingers; oils can shorten bulb life.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which bulb you’re changing

• Turn the hazard lights ON and walk around to verify it’s the front turn signal that’s out.
• Turn the ignition OFF before you put your hands behind the lamp.

Step 2: Get access at the front fender liner

• For easiest access, use a floor jack (rated 3-ton minimum) and support with jack stands (rated 3-ton minimum).
• If removing the wheel: use a 21mm socket and 1/2" drive ratchet to remove the lug nuts, then remove the wheel.
• Use a trim clip removal tool (a small pry tool made to pop plastic clips without breaking them) to remove the plastic clips holding the front portion of the fender liner.
• If your liner has screws: remove them with a Phillips screwdriver #2.
• Gently pull the liner back enough to reach behind the headlamp. Use a flashlight.

Step 3: Remove the turn signal bulb socket

• Reach behind the headlamp and locate the turn signal socket (it will twist out of the housing).
• Twist the socket counterclockwise by hand. If it’s tight, use nitrile gloves for grip.
• Pull the socket straight out.

Step 4: Replace the bulb

• Remove the bulb from the socket (most pull straight out). If it has a locking motion, rotate it slightly while pulling.
• Match the replacement bulb to the old one by checking the number stamped on the bulb base.
• Install the new bulb fully into the socket.
• Tip: Replace both sides for even brightness.

Step 5: Reinstall the socket and reassemble

• Reinsert the socket into the headlamp and twist clockwise until it locks.
• Reposition the fender liner and reinstall clips with the trim clip removal tool (push the clip body in, then press the center pin to lock).
• If removed, reinstall the wheel and hand-start lug nuts.
• Lower the vehicle, then snug lug nuts with the 21mm socket and 1/2" drive ratchet in a star pattern.

✅ After Repair

• Turn hazards ON and confirm the new front turn signal flashes normally.
• Check that the bulb is seated (no flicker) and the socket is locked (no water entry).
• If it still doesn’t work: swap the bulb to the other side to confirm bulb vs wiring/socket issue.
