🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the headlight access covers

• Use the hood release inside the cabin, then lift the hood and set the hood prop.
• Use a flashlight to look behind each headlight assembly.
• Find the round plastic dust cap behind the low-beam bulb area.
• Work on one side at a time.

Step 2: Remove the driver-side dust cap

• Use your gloved hand to rotate the round dust cap counterclockwise.
• Pull the cap straight rearward and set it aside on a clean microfiber towel.
• If the cap is tight, use a clean microfiber towel for better grip.

Step 3: Disconnect the driver-side bulb connector

• Use your gloved fingers to press the locking tab on the electrical connector.
• Pull the connector straight back from the bulb.
• If the connector is stuck, use a small flat-blade screwdriver to gently lift the lock tab while pulling the connector rearward.
• Do not pull on the wires.

Step 4: Remove the driver-side old bulb

• Use your gloved hand to rotate the bulb counterclockwise about a quarter turn.
• Pull the bulb straight out of the headlight housing.
• Keep the bulb level so it does not bump the reflector or lens inside the housing.

Step 5: Install the driver-side new bulb

• Use nitrile gloves to hold the new bulb by the plastic base only.
• Line up the bulb tabs with the slots in the headlight housing.
• Push the bulb straight in, then rotate it clockwise until it locks firmly.
• No torque spec applies; this bulb locks by hand pressure only.
• Never touch the glass.

Step 6: Reconnect the driver-side bulb connector

• Use your gloved hand to push the electrical connector onto the new bulb until it clicks.
• Gently tug the connector to make sure it is locked in place.

Step 7: Reinstall the driver-side dust cap

• Use your gloved hand to place the dust cap back over the opening.
• Rotate the cap clockwise until it seats fully.
• Make sure the cap is sealed evenly to keep moisture out of the headlight.

Step 8: Replace the passenger-side bulb

• Use the flashlight to locate the passenger-side round dust cap behind the headlight.
• Use your gloved hand to rotate the dust cap counterclockwise and remove it.
• Use your gloved fingers, or a small flat-blade screwdriver if needed, to release the connector lock.
• Pull the connector straight back from the bulb.
• Rotate the old bulb counterclockwise and pull it out.
• Install the new bulb by lining up the tabs, pushing it straight in, and rotating clockwise until locked.
• Reconnect the connector until it clicks.
• Reinstall the dust cap and rotate it clockwise until fully seated.

Step 9: Test both headlights

• Use the headlight switch to turn the low beams ON.
• Stand in front of your Tucson and confirm both low beams are working.
• Switch between low beam and high beam to make sure the correct bulbs were replaced.
• If one side does not work, turn the lights OFF and use your gloved hand to check that the connector is fully clicked into place.
