📋 Before You Begin

• Park your Tucson on level ground.
• Shift to Park and set the parking brake.
• Turn all exterior lights off.
• Open the hood and support it fully.
• A bulb socket is the plastic holder that twists into the back of the lamp housing and holds the bulb.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to pull the hood release inside the cabin.
• Use your hand to release the secondary hood latch at the front of the hood.
• Raise the hood and secure it with the prop rod.
• Put on safety glasses and nitrile gloves.

Step 2: Locate the Front Turn Signal Bulb Socket

• Use a flashlight to look behind the headlamp assembly.
• The front turn signal bulb socket is mounted at the rear of the headlamp housing, toward the outer/front corner area.
• Look for the socket that lines up with the amber turn signal lens area.
• Work slowly; space is tight.

Step 3: Remove the Bulb Socket

• Use your gloved hand to grip the turn signal bulb socket.
• Turn the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the headlamp housing.
• Do not pull on the wiring harness.

Step 4: Remove the Old Bulb

• Use your gloved hand to remove the old bulb from the socket.
• If it is a wedge-style bulb, pull it straight out.
• If it is a bayonet-style bulb, gently push in, twist counterclockwise, then pull it out. A bayonet bulb has small side pins that lock into the socket.
• Use a clean microfiber cloth if the bulb is slippery.

Step 5: Install the New Bulb

• Use nitrile gloves or a clean microfiber cloth to handle the new front turn signal bulb.
• Install the new bulb into the socket the same way the old one came out.
• Make sure the bulb is fully seated and straight in the socket.
• No torque spec applies; this bulb is hand-installed only.

Step 6: Test the Bulb Before Reassembly

• Use your hand to switch the ignition to ON without starting the engine.
• Use the turn signal stalk to activate the side you replaced.
• Check that the new front turn signal bulb flashes normally.
• Turn the ignition and turn signal back off before continuing.

Step 7: Reinstall the Bulb Socket

• Use your gloved hand to insert the bulb socket back into the headlamp housing.
• Align the tabs on the socket with the slots in the housing.
• Turn the socket clockwise until it locks in place.
• No torque spec applies; hand-tighten only until seated.

Step 8: Repeat on the Other Side

• Use the same steps to replace the opposite front turn signal bulb if replacing in pairs.
• Use a flashlight to confirm both sockets are locked into the housings.
• Replacing both sides keeps brightness even.

Step 9: Final Light Check

• Use the turn signal stalk to test the left and right front turn signals.
• Use the hazard switch to test both front turn signals together.
• Confirm the dash indicator no longer flashes rapidly.
• Close the hood securely by hand.

✅ After Repair

• ✅ If one side still does not work, recheck that the bulb is seated fully in the socket.
• ✅ If the bulb flashes quickly after replacement, inspect the rear turn signal bulb on the same side too.
• ✅ No scan tool, reset, or programming is required.
