🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb location

• Use a flashlight and look behind the headlamp assembly on the side you’re replacing.
• Find the turn signal bulb socket (it’s the socket that twists out of the headlamp housing).
• If you’re unsure, turn the hazards on briefly, then off, and identify the section that was flashing.

Step 2: Remove the turn signal bulb socket

• Put on nitrile gloves and safety glasses.
• Grip the turn signal bulb socket and rotate it about a quarter-turn counterclockwise by hand.
• Pull the socket straight back to remove it from the headlamp housing.

Step 3: Remove the old bulb from the socket

• Use a clean paper towel to hold the bulb.
• Pull the bulb straight out of the socket (it’s a push-in style).
• Check the stamping on the old bulb base (this confirms the exact bulb type).

Step 4: Install the new bulb

• Use nitrile gloves or a clean paper towel so you don’t touch the glass.
• Push the new bulb straight into the socket until fully seated.
• Tip: If it feels loose, it’s not seated.

Step 5: Reinstall the socket into the headlamp

• Align the socket tabs with the slots in the headlamp housing.
• Push the socket in, then twist clockwise by hand until it stops (snug, not forced).

Step 6: Repeat on the other side

• Use the same steps with your flashlight on the opposite headlamp.
