🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb

• Turn the hazard lights on briefly to confirm which front turn signal is out, then turn them OFF.
• Use flashlight to locate the turn signal socket at the back of the headlamp housing (it’s the socket that feeds the amber signal).

Step 2: Create access behind the headlamp

• Passenger side (typically easier): remove the front air intake snorkel if it blocks your hand.
• Use a trim clip remover (specialty) or flat-blade screwdriver to pop up the plastic push-pin clip(s) on the snorkel.
• If there’s a bolt, remove it with a 10mm socket and 1/4" drive ratchet, then lift the snorkel out.
• Driver side (often tighter): you may only need to reposition wiring slightly by hand to reach the socket; don’t pull on wires.

Step 3: Remove the turn signal bulb socket

• Reach behind the headlamp and grasp the turn signal socket.
• Rotate the socket counterclockwise about a quarter-turn by hand, then pull it straight out.
• If it’s stuck, wiggle gently.

Step 4: Replace the bulb

• Wear nitrile gloves.
• Pull the old bulb straight out of the socket (it’s a push-in style).
• Push the new amber bulb straight into the socket until fully seated.

Step 5: Reinstall the socket

• Insert the socket back into the headlamp opening, making sure it sits flush.
• Twist clockwise by hand until it locks.

Step 6: Reinstall any removed intake pieces

• Reinstall the snorkel and any clips/bolts you removed.
• If you removed a bolt, snug it using a 10mm socket and 1/4" drive ratchet (hand-tight; no torque spec required for this step).

Step 7: Test operation

• Turn ignition to ON and test left/right turn signals and hazards.
• Verify the turn signal flashes at a normal speed (fast flashing usually means a bulb still isn’t working).

✅ After Repair

• Confirm both front turn signals and hazards work.
