🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the headlight retaining pins

• Use a flashlight to locate the two vertical retaining pins at the top of the headlight assembly (they look like metal rods with a tab).
• Use a trim clip removal tool to lift up on each pin tab, then pull the pins straight up and out.
• If a pin is stubborn, use needle-nose pliers to pull upward while wiggling gently. Don’t bend the pins.

Step 2: Slide the headlight assembly forward

• With both pins removed, grasp the headlight assembly and pull it straight forward.
• If it feels stuck, use a small flathead screwdriver to gently help release the locating tabs while you pull forward. Go slow to avoid cracking the lens.

Step 3: Remove the front turn signal bulb socket

• Behind the headlight assembly, find the turn signal/park lamp socket (it’s one of the twist-lock sockets in the housing).
• Twist the socket counterclockwise by hand to unlock it, then pull it straight out.
• If it’s tight, use nitrile gloves for grip and twist firmly—no tools needed.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket (it’s a push-in bulb).
• Put on nitrile gloves and push the new amber bulb straight into the socket until fully seated.
• If you touched the glass, wipe with rubbing alcohol.

Step 5: Reinstall the socket and headlight

• Insert the socket back into the housing and twist clockwise until it locks.
• Slide the headlight assembly back into place, lining up the guide tabs.
• Reinstall the two retaining pins by pushing them straight down until fully seated.

Step 6: Repeat on the other side

• Use the same trim clip removal tool and flashlight steps to replace the bulb on the other headlight.
