🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct side

• Turn the hazard lights on briefly, then turn them back OFF.
• Walk around and note which rear turn signal is out (left or right).

Step 2: Access the tail light from the trunk

• Use a plastic trim removal tool to gently pop open the trunk side access cover (or loosen the trunk liner on the side you’re working on).
• If your ILX has plastic push-clips holding the liner, pry the center pin up with the plastic trim removal tool, then remove the clip body.

Step 3: Remove the rear turn signal bulb socket

• Locate the bulb socket going into the tail lamp (it has wires leading to it).
• Grip the socket and rotate it counterclockwise about 1/4 turn, then pull it straight out.
• Turn gently; don’t yank the wires.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new bulb by pushing it straight in until fully seated.
• Wear nitrile gloves so you don’t get oils on the bulb.

Step 5: Test before reassembly

• Reinsert the socket into the tail lamp and rotate clockwise to lock.
• Turn the ignition ON and test the turn signal and hazards.
• If it doesn’t work, turn ignition OFF and remove the bulb to reseat it firmly.

Step 6: Reinstall the trunk liner/access cover

• Reposition the trunk liner.
• Reinstall any clips by pushing the clip body in first, then press the center pin flush using your finger or the plastic trim removal tool.
• If any screws were removed, reinstall with a Phillips screwdriver #2.

Step 7: If your ILX requires tail lamp removal (only if you can’t access the socket)

• Remove the trunk liner further using the plastic trim removal tool to expose the tail lamp mounting nuts.
• Use a 10mm socket and 1/4" drive ratchet to remove the tail lamp nuts.
• Pull the tail lamp straight back to release the locating pins, then remove the bulb socket as in Step 3.
• Reinstall the tail lamp and snug the nuts evenly. Torque to 9 Nm (80 in-lbs) if using a torque wrench.

✅ After Repair
