🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct side bulb

• Turn the hazard lights ON briefly to see which front turn signal is out, then turn hazards OFF.
• Use a flashlight to locate the back of the headlight on the failed side.

Step 2: Locate the front turn signal socket

• From behind the headlight, find the socket closest to the outer corner of the headlight (toward the fender).
• Use a flashlight to clearly see the socket tabs.

Step 3: Remove the bulb socket

• Grip the socket firmly and rotate it about a quarter-turn counterclockwise by hand.
• If it’s stuck, use a nitrile gloves grip and gently help the socket start turning—do not pry on the plastic.
• Pull the socket straight out once it unlocks.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket by hand.
• Install the new 7440 amber bulb by pushing it straight into the socket until fully seated.
• If you touch glass, wipe with alcohol.

Step 5: Reinstall the socket

• Align the socket tabs with the headlight housing slots.
• Push the socket in fully, then rotate clockwise about a quarter-turn until it locks.
• Make sure the socket sits flat and snug (this helps keep water out).

Step 6: Test operation

• Turn the hazards ON and verify the front bulb flashes normally.
• If it doesn’t light, remove the socket again and confirm the bulb is pushed in all the way.

✅ After Repair

• Verify both left and right front turn signals flash at the same speed.
• Check that the bulb is amber and the socket is fully locked to prevent moisture intrusion.
• If the turn signal still “hyper-flashes,” check the other bulbs on that same side (rear turn/brake) for another burnt bulb.
