🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Liftgate

• Use your hands to fully open the liftgate.
• Stand beside the tail lamp you are replacing.
• Make sure the ignition and all exterior lights are off.

Step 2: Remove the Tail Lamp Screws

• Use a Phillips #2 screwdriver to remove the visible screws on the inner edge of the rear tail lamp assembly.
• Set the screws in a small safe spot so they do not roll away.
• Tip: A cup works great.

Step 3: Release the Tail Lamp Assembly

• Use a plastic trim removal tool at the outer edge of the lamp if it feels stuck.
• Pull the lamp straight rearward with your hands.
• Do not twist the lamp side to side; alignment pins hold it in place and can break if forced.
• Tip: Pull straight back, not outward.

Step 4: Locate the Turn Signal Bulb Socket

• Use safety glasses while working behind the lamp.
• Find the rear turn signal bulb socket on the back of the tail lamp assembly.
• The socket is the plastic piece that twists into the lamp housing and holds the bulb.

Step 5: Remove the Bulb Socket

• Use your gloved hand to turn the turn signal bulb socket counterclockwise about a quarter turn.
• Pull the socket straight out of the lamp housing.
• Do not pull on the wires.

Step 6: Replace the Bulb

• Use nitrile gloves or a clean microfiber cloth to handle the bulb.
• Pull the old bulb straight out of the socket if it is a wedge-style bulb.
• Push the new rear turn signal bulb straight into the socket until it is fully seated.
• If the bulb has metal side pins, gently press in and twist counterclockwise to remove it, then install the new bulb by pressing in and twisting clockwise.
• Tip: Match the old bulb base.

Step 7: Reinstall the Bulb Socket

• Use your gloved hand to insert the socket back into the tail lamp housing.
• Turn the socket clockwise until it locks firmly in place.
• Make sure the socket seal sits flat to help keep water out.

Step 8: Test the Turn Signal Before Reassembly

• Use the hazard switch or turn signal stalk to test the new bulb.
• Confirm the rear turn signal flashes normally.
• Turn the lights off again before reinstalling the lamp.

Step 9: Reinstall the Tail Lamp Assembly

• Use your hands to line up the lamp guide pins with the body openings.
• Push the lamp straight forward until it seats evenly against the body.
• Use the Phillips #2 screwdriver to reinstall the tail lamp screws.
• Tighten the screws snugly by hand only; Hyundai does not require heavy force here.
• Torque to snug hand-tight only; do not overtighten plastic lamp screws.

Step 10: Final Light Check

• Use the hazard switch to check both rear turn signals.
• Use the brake pedal and parking lights to make sure no wiring was disturbed.
• Close the liftgate when finished.
