🔧 Tucson - Rear Turn Signal Bulb Replacement

You’ll access the rear lamp from inside the cargo area, remove the rear lamp assembly, then swap the turn-signal bulb in its twist-lock socket. This is a simple job, but the lamp studs are easy to crack if you overtighten them.

Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

⚠️ Safety & Precautions

• ⚠️ Turn ignition OFF and remove the key before working on exterior lights.
• ⚠️ Let bulbs cool before touching; they can be very hot.
• ⚠️ Don’t touch a new glass bulb with bare fingers; oils can shorten bulb life.
• ⚠️ Support the lamp as you pull it out so you don’t scratch paint.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the access area behind the rear lamp

• Open the liftgate and go to the side you’re replacing.
• Use a plastic trim removal tool to open/remove the small interior access cover behind the rear lamp (if equipped).

Step 2: Remove the rear lamp retaining nuts

• Use a 10mm socket, 3" socket extension, and 1/4" ratchet to remove the lamp retaining nuts.
• Put the nuts somewhere safe so they don’t fall into the body cavity.

Step 3: Pull the rear lamp assembly out

• Hold the lamp with both hands and pull straight rearward to release the locating pin/clips.
• Wiggle gently; don’t pry on paint.

Step 4: Remove the turn signal bulb socket

• On the back of the lamp, find the turn-signal socket (the socket that lines up with the amber/turn section of the lens).
• Twist the socket counterclockwise by hand and pull it out.
• If it’s tight, use nitrile gloves for grip (don’t use pliers unless absolutely necessary).

Step 5: Replace the bulb

• Remove the old bulb from the socket (either pull straight out or twist-and-pull depending on bulb base).
• Install the new bulb fully into the socket.
• If using it, apply a tiny amount of dielectric grease to the socket seal (not on the bulb glass).

Step 6: Reinstall the socket and lamp

• Insert the socket back into the lamp and twist clockwise until it locks by hand.
• Line up the lamp’s locating pin/clips and press the lamp straight into place.
• Reinstall the retaining nuts using the 10mm socket and 1/4" ratchet: Torque to 5-7 Nm (44-62 in-lbs).
• Reinstall the interior access cover using the plastic trim removal tool (and Phillips screwdriver if your cover uses a screw).

✅ After Repair

• Turn ignition ON and test the rear turn signal and hazards on that side.
• Walk behind your Tucson and confirm the flash rate is normal (fast flashing usually means a bulb isn’t seated or is the wrong type).
• Make sure the lamp sits flush and doesn’t wiggle.
