Assumption: Your NX200t has serviceable front turn-signal bulbs accessed through the front wheel-well liner. If your front turn signals are LED (no removable bulb socket), the lamp/LED unit is not bulb-serviceable and replacement is typically the headlamp assembly or LED module.

🔧 NX - Front Turn Signal Bulb Replacement

You’ll remove a small section of the front wheel-well liner to reach the turn-signal bulb socket behind the headlamp. Then you’ll swap the bulb, test it, and reassemble everything to keep water and dirt out.

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

⚠️ Safety & Precautions

• 🛑 Work on level ground and chock the rear wheels.
• 🛑 Support the SUV with jack stands before reaching into the wheel well.
• 🛑 Let the headlamp area cool if lights were recently on.
• 🛑 Avoid touching the new bulb glass with bare fingers (skin oils can shorten bulb life).
• 🛑 Battery disconnect is not required for a bulb swap, but keep the light switch OFF while unplugging sockets.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the front wheel lug nuts

• Use a 21mm socket with a 1/2" drive breaker bar to loosen the lug nuts about 1/2 turn (do not remove them yet).

Step 2: Lift and support the front corner

• Use a floor jack (rated 3-ton minimum) to lift the front corner on the side you’re replacing.
• Set the SUV onto jack stands (rated 3-ton minimum).
• Shake test the vehicle before working.

Step 3: Remove the front wheel

• Remove the lug nuts with the 21mm socket and take the wheel off.

Step 4: Open the wheel-well liner access

• Use a trim clip removal tool to remove the plastic push-clips along the front portion of the fender liner.
• If equipped with screws, remove them using a Phillips screwdriver or 10mm socket with a 3/8" drive ratchet.
• Gently pull the liner back just enough to get your hand to the back of the headlamp.
• Don’t crease the liner; bend it slowly.

Step 5: Remove the turn signal bulb socket

• Use a flashlight to find the turn signal socket at the back of the headlamp.
• Grip the socket and rotate it counterclockwise about 1/4 turn by hand, then pull it straight out.

Step 6: Replace the bulb

• Pull the old bulb straight out of the socket (it’s a push-in fit).
• Install the new bulb (same type as removed) by pushing it straight into the socket.
• Wear nitrile gloves so you don’t touch the bulb glass.

Step 7: Test the turn signal

• Reinsert the socket into the headlamp and twist clockwise to lock by hand.
• Turn the ignition to ON and switch on the turn signal to confirm it flashes normally.
• If it doesn’t work, remove the socket again and re-seat the bulb firmly.

Step 8: Reassemble the wheel well and wheel

• Push the fender liner back into place and reinstall clips with the trim clip removal tool (press clips in until fully seated).
• Reinstall the wheel and hand-start the lug nuts.
• Lower the SUV using the floor jack (rated 3-ton minimum), then torque the lug nuts in a star pattern using a 1/2" drive torque wrench (20–200 ft-lbs range).
• Torque to 140 Nm (103 ft-lbs)

---

✅ After Repair

• Verify the turn signal works on that side and that the hazard lights flash evenly.
• Check the fender liner is fully secured (loose liner can rub the tire).
• Do a quick night check to confirm the light is bright and amber.
