🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the turn signal bulb socket

• Put on nitrile gloves and safety glasses.
• Use a flashlight to look behind the headlight assembly (from the engine bay).
• Find the turn signal socket (it’s a twist-lock socket on the back of the headlight).

Step 2: Remove the bulb socket from the headlight

• Use your gloved hand to grip the socket.
• Turn the socket counterclockwise about 1/4 turn, then pull it straight out.
• If tight, wiggle gently—don’t pry.

Step 3: Remove the old bulb

• Pull the old bulb straight out of the socket using your gloved fingers.
• Inspect the socket for corrosion or melting. If you see damage, stop and replace the socket too.

Step 4: Install the new bulb

• Install the new amber 7440A bulb by pushing it straight into the socket until fully seated.
• Do not touch the bulb glass with bare fingers.

Step 5: Reinstall the socket

• Insert the socket back into the headlight housing.
• Turn clockwise about 1/4 turn until it locks snugly.
• No torque spec here—hand-tight only.

Step 6: Repeat on the other side

• Repeat Steps 1–5 for the other front turn signal.
• Replace bulbs in pairs for matching brightness.

✅ After Repair
