🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb/socket

• Turn the ignition to ON and switch on the hazard lights, then turn ignition OFF.
• Use a flashlight and look behind the headlight you’re working on.
• Find the turn signal bulb socket (it’s a twist-lock socket going into the back of the headlight).

Step 2: Create working room (passenger side, if needed)

• If your hand space is tight, remove the front air intake duct/snorkel.
• Use a trim clip removal tool to pop up any plastic push-clips.
• Use a 10mm socket with a 1/4" ratchet to remove any 10mm bolts holding the duct.
• Lift the duct out and set it aside. Torque to 9 Nm (80 in-lbs) when reinstalling 10mm bolts.

Step 3: Remove the turn signal bulb socket

• Put on nitrile gloves and safety glasses.
• Reach behind the headlight and grasp the turn signal socket.
• Rotate the socket counterclockwise about 1/4 turn by hand, then pull it straight out.

Step 4: Remove the old bulb

• Pull the old bulb straight out of the socket by hand.
• If it’s stubborn, wiggle gently while pulling—don’t twist hard.

Step 5: Install the new bulb

• Install the new amber 7440A bulb by pushing it straight into the socket until fully seated.
• Avoid touching the glass. If you accidentally touch it, wipe it clean and dry.

Step 6: Reinstall the socket and test

• Insert the socket back into the headlight housing.
• Twist clockwise about 1/4 turn until it locks snugly by hand (do not over-tighten).
• Turn ignition ON and test the turn signal and hazards to confirm normal flash rate.

Step 7: Reinstall any removed duct/clips

• Reinstall the intake duct/snorkel (if removed).
• Use a 10mm socket and 1/4" ratchet for bolts. Torque to 9 Nm (80 in-lbs).
• Reinstall push-clips using the trim clip removal tool to align them first, then press them in.

✅ After Repair

• Verify both front turn signals flash at a normal speed on left and right.
• Check that the bulb is amber and evenly lit (no flicker).
• If the signal flashes fast, re-check the bulb is fully seated and the socket is locked.
