🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the turn signal bulb socket

• Use a flashlight and look behind the headlight assembly (from the engine bay).
• Find the socket going into the headlight housing for the turn signal (it’s one of the smaller twist-in sockets).

Step 2: Make room (if access is tight)

• If your hand doesn’t fit, remove the nearby intake duct/cover fasteners using a 10mm socket, 1/4" ratchet, and short extension (3").
• If plastic clips are in the way, pop them up with a trim clip remover (this tool lifts the clip without breaking it).
• Only remove what you need for hand clearance.

Step 3: Remove the bulb socket

• Put on nitrile gloves and safety glasses.
• Grab the socket and rotate it about a 1/4 turn counterclockwise by hand.
• Pull the socket straight out of the headlight housing.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket (it’s a push-in “wedge” style bulb).
• Push the new front turn signal bulb (amber) straight into the socket until fully seated.
• If you touched the glass, wipe with rubbing alcohol.

Step 5: Reinstall the socket

• Insert the socket back into the housing, making sure the tabs line up.
• Turn the socket clockwise about a 1/4 turn until it locks snugly (hand-tight only).

Step 6: Reinstall any parts you moved

• Reinstall any ducting/covers you loosened using the 10mm socket, 1/4" ratchet, and short extension (3").
• Reinstall plastic clips with the trim clip remover (press the clip body in, then press the center pin down).

Step 7: Repeat on the other side

• Replace the bulb on the opposite headlight the same way.
• Replacing in pairs keeps brightness/color consistent.

✅ After Repair
