🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify the turn signal bulb socket

• Use a flashlight and look behind the headlamp assembly.
• Find the socket that goes to the turn signal area (typically the amber section of the headlamp lens).
• Tip: Turn on hazards briefly to confirm.
• Turn hazards back OFF before removing anything.

Step 2: Remove the bulb socket from the headlamp

• Put on nitrile gloves and safety glasses.
• Grip the socket and rotate it about 1/4 turn counterclockwise by hand, then pull it straight out.

Step 3: Remove the old bulb from the socket

• Pull the bulb straight out of the socket by hand.
• If it’s stuck, use a clean shop towel to improve grip and pull straight (don’t twist hard).

Step 4: Install the new bulb

• Using nitrile gloves, push the new bulb straight into the socket until fully seated.
• If you accidentally touch the glass, wipe it with a clean shop towel before installing.

Step 5: Reinstall the socket

• Insert the socket back into the headlamp housing.
• Rotate it about 1/4 turn clockwise by hand until it locks in place.
• Gently tug the socket to confirm it’s secure.

Step 6: Repeat on the other side

• Repeat Steps 1–5 for the opposite front turn signal.
• Tip: Replace both sides together for matching brightness.
