🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb is out

• Turn on the hazard lights, then walk around the vehicle and confirm which front turn signal is not flashing.
• Turn hazards OFF before you start disassembly.

Step 2: Open the hood and locate the turn signal bulb socket

• Open the hood and use a flashlight to look behind the headlamp on the side you’re replacing.
• Find the turn signal bulb socket (a round plastic socket going into the back of the headlamp).

Step 3: Remove the bulb socket from the headlamp

• Grip the socket firmly (use nitrile gloves for grip).
• Rotate the socket about 1/4 turn counterclockwise, then pull it straight out.
• If your hands don’t fit well, use a flashlight and reposition wiring gently—do not yank on wires.

Step 4: Remove the old bulb from the socket

• Pull the bulb straight out of the socket (it’s a push-in wedge style).
• If it’s stuck, wiggle it gently while pulling—don’t crush the bulb.

Step 5: Install the new bulb

• Push the new amber bulb straight into the socket until fully seated.
• Use nitrile gloves to keep oils/dirt off the bulb and socket.

Step 6: Reinstall the socket and test

• Insert the socket back into the headlamp, making sure it sits flush.
• Rotate the socket clockwise about 1/4 turn until it locks.
• Turn on the hazards and confirm the new front turn signal flashes normally.

Step 7: Repeat on the other side (recommended)

• Replace the other front turn signal bulb the same way.
• Replacing in pairs helps avoid mismatched brightness/color.

✅ After Repair

• Verify left and right turn signals work from the stalk.
• Verify hazards work and both front turn signals flash at the same speed.
• If it “hyper-flashes” (very fast blinking), re-seat the bulb and socket and re-test.
