⚠️ Safety & Precautions

• ⚠️ Let headlights cool first; bulbs get very hot.
• ⚠️ Do not touch the new bulb glass with bare fingers; skin oil can shorten bulb life. Use clean gloves.
• ⚠️ If your Sorento has HID (xenon): there is high voltage at the ballast. Turn lights OFF and disconnect the battery negative terminal before touching the rear of the headlamp.
• ⚠️ Support the hood securely and keep tools away from the radiator fan area.

📋 Before You Begin

• Park on level ground, shift to Park, and turn the headlights OFF.
• Open the hood and use a flashlight to identify the rear covers/connectors on each headlamp.
• If equipped with HID (xenon) low beams: disconnect the battery negative terminal using a 10mm socket.
• Quick check: the low beam is usually the larger rear cover; the high beam is often a smaller socket closer to the inner side of the housing.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which bulb you’re replacing (low vs high)

• Use a flashlight and look behind the headlight: you’ll see bulb sockets/covers.
• Turn the headlight switch ON briefly to confirm which side is out, then switch OFF.
• Replacing both sides in pairs is best.

Step 2: Make room if access is tight

• If your hand won’t fit, remove nearby plastic ducting/covers using a trim clip removal tool.
• If there are 10mm fasteners, remove them with a 10mm socket, 1/4" ratchet, and 6" extension.
• Reinstall those 10mm fasteners later Torque to 7 Nm (62 in-lbs).

Step 3: Remove the rear dust cover (if equipped)

• Put on nitrile gloves and safety glasses.
• Twist the rear cover counterclockwise by hand and pull it off (some covers pull straight off).

Step 4: Disconnect the bulb connector

• Press the connector lock tab and pull the connector straight off the bulb.
• If it’s stuck, wiggle gently—do not pull on the wires.

Step 5: Remove the bulb

• If it’s a twist-lock bulb: rotate the bulb counterclockwise and pull it out.
• If it uses a metal retaining clip: push the clip in and swing it down, then remove the bulb.
• Keep note of the bulb’s orientation so the new one seats the same way.

Step 6: Install the new bulb (do not touch the glass)

• With nitrile gloves, insert the new bulb in the same orientation.
• Lock it in place by twisting clockwise or re-securing the retaining clip.
• If you accidentally touch the glass, clean it with rubbing alcohol and let it dry before installing.

Step 7: Reconnect and seal everything

• Push the electrical connector on until it clicks.
• Reinstall the rear dust cover and twist it fully closed to keep moisture out.
• Reinstall any ducts/covers you moved using the trim clip removal tool and 10mm socket.
• For any 10mm fasteners reinstalled: Torque to 7 Nm (62 in-lbs).

Step 8: Repeat on the other headlight

• Do the same bulb on the opposite side so brightness/color match.

✅ After Repair

• Turn headlights ON and verify low beam and high beam operation on both sides.
