🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the Headlight Bulb Covers

• Use a flashlight to look behind each front headlight housing.
• Find the round rear access cover behind the low-beam bulb area.
• The access cover keeps dirt and moisture out of the headlight housing.
• Start with the easier side first.

Step 2: Make Extra Room if Needed

• Use your flashlight to check the space behind the driver-side headlight.
• If the air intake duct blocks your hand, use a 10mm socket and 1/4-inch ratchet to remove the small retaining bolt.
• If a plastic push clip is installed, use a flathead screwdriver to gently lift the center pin, then pull the clip out by hand.
• Move the duct just enough to reach the rear headlight cover.
• Plastic clips break easily.

Step 3: Remove the Driver-Side Rear Cover

• Use your hand to turn the round rear headlight cover counterclockwise.
• Pull the cover straight off the headlight housing.
• Place the cover on a clean microfiber towel.

Step 4: Disconnect the Driver-Side Bulb Connector

• Use your fingers to press the locking tab on the electrical connector.
• Pull the connector straight back from the bulb.
• If it is stuck, use a flathead screwdriver to gently press the locking tab while pulling on the connector body.
• Do not pull on the wires.

Step 5: Remove the Driver-Side Old Bulb

• Use your hand to rotate the bulb base counterclockwise until it unlocks.
• Pull the bulb straight out of the headlight housing.
• Look at the locking tabs on the old bulb base so you understand how the new bulb fits.

Step 6: Install the Driver-Side New Bulb

• Use nitrile gloves before opening and handling the new bulb.
• Hold the new bulb by the plastic base only.
• Do not touch the glass.
• If the glass is touched, use a clean microfiber towel to wipe it clean before installation.
• Insert the new bulb straight into the headlight housing.
• Use your hand to rotate the bulb clockwise until it locks in place.
• No torque spec is used because the bulb is hand-locked only.

Step 7: Reconnect the Driver-Side Bulb

• Use your fingers to push the electrical connector straight onto the new bulb.
• Listen or feel for a click from the connector lock.
• Use a very small amount of dielectric grease around the connector seal if desired.
• Do not pack grease into the metal terminals.

Step 8: Reinstall the Driver-Side Rear Cover

• Use your hand to place the rear cover squarely onto the headlight housing.
• Turn the cover clockwise until it is fully seated.
• Use your flashlight to check that the cover sits flat all the way around.

Step 9: Replace the Passenger-Side Bulb

• Use your flashlight to locate the passenger-side rear headlight cover.
• Use your hand to turn the cover counterclockwise and remove it.
• Use your fingers to press the connector tab and pull the connector straight back.
• Use your hand to rotate the old bulb counterclockwise and remove it.
• Use nitrile gloves to handle the new bulb by the plastic base only.
• Insert the new bulb straight into the housing.
• Use your hand to rotate the bulb clockwise until it locks.
• Push the connector on until it clicks.
• Use your hand to reinstall the rear cover clockwise until fully seated.

Step 10: Reinstall Any Removed Access Parts

• If you moved the air intake duct, position it back in place by hand.
• Use a 10mm socket and 1/4-inch ratchet to reinstall the retaining bolt.
• Torque to 5-7 Nm (44-62 in-lbs).
• If you removed a plastic push clip, press it back into place by hand.

Step 11: Test the Headlights

• Turn the headlight switch to low beam.
• Walk to the front of your Tucson and confirm both headlights turn on.
• Turn the headlights OFF after testing.
• If one side does not work, turn the lights OFF and recheck that bulb connector.
