🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Liftgate

• Use your hand to open the rear liftgate fully.
• Make sure the liftgate is stable and not trying to close while you work.
• Good lighting helps avoid dropped screws.

Step 2: Remove the Inner Tail Lamp Fasteners

• Use the T30 Torx screwdriver to remove the two Torx screws on the inner edge of the tail lamp assembly.
• Set the screws somewhere safe so they do not roll away.
• A Torx screwdriver has a star-shaped tip that fits Jeep’s tail lamp screws.

Step 3: Release the Tail Lamp Assembly

• Use the trim panel removal tool at the outer edge of the tail lamp to gently help release the locating pins.
• A trim panel removal tool is a plastic pry tool that helps prevent paint and lens damage.
• Pull the lamp straight rearward with both hands.
• Do not twist the lamp hard; the outer side uses guide pins that can crack if forced sideways.
• Pull straight back, not outward.

Step 4: Locate the Rear Turn Signal Bulb Socket

• Use your hands to support the lamp so the wiring is not stretched.
• Find the turn signal bulb socket on the back of the tail lamp assembly.
• The turn signal socket is typically the amber bulb position in the rear lamp cluster.

Step 5: Remove the Old Bulb

• Use your hand to rotate the bulb socket counterclockwise about a quarter turn.
• Pull the socket straight out of the lamp housing.
• Use clean nitrile gloves to pull the old bulb straight out of the socket.
• If the bulb is stuck, gently wiggle it while pulling straight out.

Step 6: Install the New Bulb

• Use clean nitrile gloves to push the new rear turn signal bulb straight into the socket until it seats fully.
• If you accidentally touch the glass, wipe it clean with a clean microfiber cloth.
• Do not use tools to force the bulb into the socket.

Step 7: Reinstall the Bulb Socket

• Use your hand to insert the bulb socket back into the tail lamp housing.
• Rotate the socket clockwise until it locks in place.
• Make sure the socket seal sits flat to help keep water out.

Step 8: Test the Turn Signal Before Final Assembly

• Use the turn signal stalk or hazard switch to test the new bulb.
• Confirm the rear turn signal flashes normally.
• Turn the signal or hazards off before reinstalling the lamp.
• If it does not light, remove the bulb with your gloved hand, rotate it 180 degrees if applicable, reinstall it, and test again.

Step 9: Reinstall the Tail Lamp Assembly

• Use both hands to line up the tail lamp guide pins with the body openings.
• Push the lamp straight forward until it seats evenly against the body.
• Make sure the gaps around the lamp look even.

Step 10: Reinstall the Tail Lamp Screws

• Use the T30 Torx screwdriver to reinstall the two tail lamp screws.
• Tighten them snugly by hand only.
• Torque to 3 Nm (27 in-lbs)
• Do not overtighten; the lamp housing can crack.

✅ After Repair

• ✅ Check that the tail lamp sits flush and does not feel loose.
