🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Make room to reach behind the headlight

• Use a flashlight to locate the back of the headlight assembly on the side you’re working on.
• If your hands don’t fit comfortably, remove the front air duct/snorkel near the radiator support:
• Use a trim clip removal tool (a forked tool that pops plastic fasteners out) or flat-blade screwdriver to lift the center of the plastic push-clips, then remove the clips.
• If there are 10mm bolts holding the duct/bracket, remove them with a 10mm socket, 1/4" ratchet, and 6" extension.
• Tip: Put clips/bolts in a cup.

Step 2: (Passenger side) Move the washer filler neck if it blocks access

• If the windshield washer filler neck is in the way, grip it and gently work it upward while twisting by hand to pull it out of its grommet.
• Set it aside without kinking any hoses.
• Use nitrile gloves and safety glasses while working in tight spaces.

Step 3: Remove the turn signal bulb socket

• From behind the headlight, find the turn signal socket (a round twist-in socket going into the headlight housing).
• Turn the socket counterclockwise about a quarter turn to unlock it, then pull it straight back.
• If it’s tight, use your gloved hand for better grip; avoid prying hard on the headlight housing.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new 7440A / amber bulb by pushing it straight into the socket until fully seated.
• Tip: Don’t touch the bulb glass.

Step 5: Reinstall the socket

• Insert the socket back into the headlight housing, making sure the tabs line up.
• Turn the socket clockwise to lock it (snug by hand; no tools needed).

Step 6: Reinstall anything you moved

• Reinstall the washer filler neck (passenger side) by pressing it back into its grommet until fully seated.
• Reinstall the air duct/snorkel and any brackets.
• Reinstall push-clips by pushing the outer body in first, then pressing the center pin down.
• If you removed 10mm bolts, reinstall them with a 10mm socket, 1/4" ratchet, and 6" extension (snug; do not over-tighten into plastic).

Step 7: Repeat on the other side

• Repeat Steps 1–6 for the other front turn signal so both bulbs match in brightness and color.

✅ After Repair

• Turn the ignition to ON and test left and right turn signals.
• Turn on the hazard lights and confirm both front signals flash evenly.
• If the dash indicator “fast blinks,” that usually means a bulb isn’t seated, the wrong bulb type was installed, or a bulb is out.
