🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Rear Hatch

• Lift the rear hatch fully.
• Stand behind your Tucson and look at the inner edge of each tail lamp assembly.
• You should see retaining screws along the hatch-side edge of the lamp.

Step 2: Remove the Tail Lamp Screws

• Use a Phillips #2 screwdriver to remove the screws holding the driver-side tail lamp assembly.
• Place the screws somewhere safe so they do not roll away.
• Repeat this on the passenger-side tail lamp assembly.
• Tip: Take a phone photo first.

Step 3: Pull the Tail Lamp Assembly Straight Back

• Use both hands to gently pull the driver-side tail lamp assembly straight rearward.
• If it feels stuck, use a plastic trim removal tool at the outer edge to gently help release the alignment pins.
• Do not twist the lamp hard; the plastic guide pins can crack.
• Repeat this on the passenger side.

Step 4: Locate the Tail Light Bulb Socket

• Look at the back of the removed tail lamp assembly.
• Find the tail light bulb socket. The socket is the plastic holder that twists into the lamp housing.
• Use your hand to turn the bulb socket counterclockwise about a quarter turn.
• Pull the socket straight out of the lamp housing.

Step 5: Remove the Old Bulb

• Wear nitrile gloves before touching the bulb.
• Pull the old bulb straight out of the socket if it is a wedge-style bulb.
• If the bulb has locking pins, press it inward slightly and turn it counterclockwise to release it.
• Use a clean microfiber cloth if the bulb is difficult to grip.

Step 6: Install the New Bulb

• Use nitrile gloves or a clean microfiber cloth to handle the new tail light bulb.
• Install the new bulb into the socket the same way the old one came out.
• Make sure it is fully seated and straight.
• Tip: Do not touch glass with bare fingers.

Step 7: Reinstall the Bulb Socket

• Insert the bulb socket back into the tail lamp housing.
• Turn the socket clockwise by hand until it locks in place.
• Do not use pliers; hand-tight is correct for this plastic socket.

Step 8: Test the New Bulbs

• Before reinstalling the tail lamp assemblies, turn the parking lights on.
• Check that both new tail light bulbs illuminate.
• Press the brake pedal and confirm the brake lights work if the same bulb also handles brake-light function.
• Turn the lights back off after testing.

Step 9: Reinstall the Tail Lamp Assemblies

• Align the guide pins on the tail lamp assembly with the body openings.
• Push the lamp straight forward until it sits flush with the body.
• Use the Phillips #2 screwdriver to reinstall the retaining screws.
• Tighten the screws snugly by hand; do not overtighten because the lamp housing is plastic.

Step 10: Final Light Check

• Turn the parking lights on again and confirm both tail lights work.
• Check the brake lights, turn signals, reverse lights, and hazard lights before driving.
• Close the rear hatch securely.
