🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open access to the headlamp area

• Open the hood and secure it.
• Use a flat-blade trim tool to gently move any plastic covers or intake ducting that blocks rear headlamp access, if equipped.
• Go slow to avoid breaking clips.

Step 2: Remove the turn signal bulb access cap

• Locate the rear access cover on the back of the headlamp assembly.
• Use a flat-blade trim tool or your hand to release the cap.
• Set the cap aside in a clean spot.

Step 3: Remove the old bulb

• Grip the bulb socket and twist it counterclockwise by hand, or use a small pick tool if the socket is stuck.
• Pull the bulb/socket straight out.
• Remove the bulb from the socket by pulling it out or twisting it free, depending on bulb style.

Step 4: Install the new bulb

• Compare the new bulb to the old one before installing.
• Install the new bulb into the socket with clean hands or nitrile gloves.
• Push the socket back into the headlamp and twist clockwise to lock it in place.

Step 5: Reassemble and test

• Reinstall the access cap by hand until fully seated.
• Put any removed ducting or covers back in place using the flat-blade trim tool if needed.
• Turn the ignition on and test the turn signal, hazard lights, and parking lights.
