🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open access to the back of the headlamp

• Open the hood and locate the rear of the headlight assembly.
• If the engine cover blocks access, lift it straight up by hand. It snaps on and off.
• Work gently on plastic clips.

Step 2: Remove the turn signal bulb socket

• Reach behind the headlamp and find the turn signal bulb socket.
• Twist the socket counterclockwise by hand to unlock it.
• Pull the socket straight out of the housing.
• No torque spec applies here; it is a twist-lock fit.

Step 3: Replace the bulb

• Twist the old bulb counterclockwise and remove it from the socket, or pull it straight out if your socket style is push-in.
• Install the new bulb using clean gloves.
• Make sure the bulb is fully seated.
• Do not touch the glass.

Step 4: Reinstall the socket

• Insert the socket back into the headlamp housing.
• Twist it clockwise by hand until it locks in place.
• Confirm it feels snug and fully seated.

Step 5: Test the new bulb

• Turn the key to ON.
• Turn on the turn signal and check the repaired side.
• Make sure the bulb flashes normally and the lens is secure.
