⚠️ Safety & Precautions

• Turn the ignition OFF and set the parking brake before starting.
• Let bulbs cool first; they can be hot right after use.
• Do not touch the new bulb’s glass with bare fingers; oil can shorten bulb life.
• Support the lamp as you remove it so it doesn’t drop and crack.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the rear lamp fasteners

• Open the liftgate.
• Locate the rear lamp screws on the inboard edge of the lamp (the side closest to the liftgate opening).
• Use a flashlight to clearly see the screw heads.

Step 2: Remove the rear lamp assembly (common method)

• Use a Phillips screwdriver #2 to remove the lamp retaining screws.
• Gently work a plastic trim removal tool set behind the lamp edge and pull the lamp straight rearward to release the locating pins.
• Pull straight back, not outward.
• If it feels stuck, re-check that all screws are fully removed before pulling harder.

Step 3: Remove the turn signal bulb socket

• Support the lamp with one hand.
• Find the turn signal bulb socket on the back of the lamp.
• Twist the socket counterclockwise by hand and pull it out of the lamp.
• If space is tight, use a flashlight to confirm you’re turning the correct socket.

Step 4: Replace the bulb

• Put on clean nitrile gloves.
• Pull the old bulb straight out of the socket by hand.
• Push the new bulb straight into the socket until fully seated.
• Do not touch the bulb glass with bare skin.

Step 5: Reinstall the socket and lamp

• Insert the socket back into the lamp and twist clockwise by hand until it stops.
• Line up the lamp locating pins with the body holes, then push the lamp straight inward until it seats flush.
• Reinstall the screws using a Phillips screwdriver #2 and tighten snug.
• Torque: No reliable published spec for this fastener in this context; tighten snug (do not overtighten).

Step 6: Alternate access method (if your Tucson has an interior access cover)

• If you see a small access panel behind the lamp area inside the cargo trim, use a plastic trim removal tool set to carefully pop the cover open.
• Reach in and twist the turn signal socket counterclockwise by hand, then replace the bulb as in Step 4.
• Reinstall the access cover by pressing it back into place.

✅ After Repair

• Turn ignition ON and test left/right turn signals and hazard lights.
• Verify the blink rate is normal (a fast blink usually means a bulb still isn’t working).
• Confirm the lamp sits flush and doesn’t wiggle.
