🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the turn signal socket behind the headlight

• Use your flashlight to look behind the headlight assembly on the side you’re replacing.
• Find the turn/park bulb socket (it will be a twist-lock socket going into the back of the headlight housing).
• Turn signal socket is usually the outer/lower one.

Step 2: Remove the bulb socket from the headlight housing

• Use nitrile gloves for grip and to keep oils off parts.
• Twist the socket counterclockwise about 1/4 turn until it unlocks.
• Pull the socket straight back to remove it from the housing.

Step 3: Remove the old bulb from the socket

• Use your shop towel to hold the bulb and socket (better grip).
• Pull the bulb straight out of the socket (it’s a wedge base, meaning it’s held by friction, not threads).
• If it’s stuck, use the small flathead screwdriver gently to help pry while pulling straight out (do not crack the socket).

Step 4: Install the new bulb

• Use nitrile gloves to handle the new bulb.
• Push the new bulb straight into the socket until fully seated.
• Seat it firmly; a loose bulb flickers.

Step 5: Reinstall the socket into the headlight housing

• Use your flashlight to line up the socket tabs with the slots in the housing.
• Insert the socket, then twist clockwise about 1/4 turn until it locks snugly.
• Do not overtighten—twist-lock sockets just need to be fully seated.

Step 6: Repeat on the other side (recommended)

• Use your flashlight and repeat Steps 1–5 for the other front turn signal.
• Replace in pairs for matching brightness and color.
