🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and access the headlamp area

• Use the hood release inside the cab, then raise the hood fully.
• Locate the back of the headlamp assembly behind each front corner.

Step 2: Remove the upper headlamp retainers

• Use a 7mm socket and 1/4-inch ratchet to remove the upper fasteners around the headlamp support area if they block access.
• Keep the fasteners in a safe place.
• Work gently around the plastic tabs.

Step 3: Access the bulb socket

• Reach behind the headlamp assembly and locate the turn signal bulb socket.
• Rotate the socket counterclockwise by hand to unlock it, then pull it straight out.
• If it is stuck, wiggle it gently. Do not force it.

Step 4: Replace the bulb

• Remove the old bulb from the socket by pulling it straight out.
• Install the new front turn signal bulb into the socket.
• Make sure the bulb is fully seated.
• Do not touch the glass part of the bulb.

Step 5: Reinstall the socket

• Insert the socket back into the headlamp housing.
• Turn it clockwise by hand until it locks.
• Make sure it sits snugly and evenly.

Step 6: Reassemble any removed trim or fasteners

• If you removed any upper retainers, reinstall them using the 7mm socket and 1/4-inch ratchet.
• Tighten securely, but do not overtighten plastic parts.
• Snug is enough on plastic fasteners.

Step 7: Test the new bulb

• Turn the ignition on.
• Activate the left and right turn signals one at a time.
• Confirm the new bulb flashes normally.
