• ⚠️ Turn ignition OFF and remove the key before unplugging any bulbs.
• ⚠️ Do not touch the new bulb glass with bare fingers; skin oils can shorten bulb life.
• ⚠️ Support the hood securely and keep loose clothing away from the radiator fan area.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb location

• Use a flashlight to look behind the headlight assembly from the engine bay.
• Find the turn signal socket (it will be a smaller socket going into the headlight housing).
• Tip: Turn signals are usually the amber bulb.

Step 2: Make room for your hand (if needed)

• If access is tight, use a trim clip removal tool to pop up any plastic push-clips on the nearby intake duct/upper cover.
• Use a Phillips screwdriver #2 to remove any Phillips screws holding the plastic ducting (only if present).
• Move the plastic piece slightly aside to create a clear path to the bulb socket.
• Tip: Set clips in the towel so they don’t disappear.

Step 3: Remove the turn signal bulb socket

• Put on nitrile gloves and safety glasses.
• Grip the socket firmly and twist it counterclockwise about 1/4 turn, then pull it straight out.
• If it’s stubborn, use the microfiber towel for extra grip (do not use pliers).

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new front turn signal bulb (amber) by pushing it straight in until fully seated.
• If you accidentally touch the bulb glass, wipe it clean with the microfiber towel.
• Tip: Push straight—don’t wiggle hard.

Step 5: Reinstall the socket

• Insert the socket back into the headlight housing.
• Twist clockwise about 1/4 turn until it locks in place (snug, not forced).

Step 6: Test the turn signal

• Turn the ignition to ON and switch on the turn signal for that side.
• Walk to the front and confirm it flashes normally.
• Repeat Steps 2–6 on the other side.

Step 7: Reinstall any removed covers/clips

• Reposition any plastic ducting/trim you moved.
• Reinstall screws with a Phillips screwdriver #2.
• Press push-clips back in by hand (pin down last if it’s the two-piece style).

✅ After Repair

• Verify both front turn signals flash at a normal speed on the dash and outside.
• Turn on the hazard lights and confirm both front bulbs flash evenly.
• If one side “hyperflashes” (very fast), that usually means a bulb isn’t seated or another turn signal bulb is out.
