🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the taillight screws

• Open the tailgate.
• Remove the two screws on the inboard edge of the taillight using a Phillips #2 screwdriver.
• If your screws are star-shaped instead, use a Torx T20 screwdriver instead of Phillips.
• Keep screws somewhere safe.

Step 2: Pull the taillight housing out

• Grip the taillight housing and pull it straight rearward.
• If it feels stuck, gently work it free with a trim/panel removal tool (a non-marring plastic pry tool).
• Do not pry hard against painted surfaces; use a clean rag as a buffer if needed.

Step 3: Remove the bulb socket

• Locate the socket for the bulb you’re replacing (stop/turn/tail or reverse).
• Twist the socket counterclockwise by hand and pull it out of the housing.

Step 4: Replace the bulb

• Wear nitrile gloves.
• Pull the old bulb straight out of the socket by hand.
• Push the new bulb straight into the socket until fully seated.
• If you accidentally touch the glass, wipe it with a clean rag.

Step 5: Reinstall the socket and housing

• Reinsert the socket into the housing and twist clockwise to lock by hand.
• Align the taillight housing locating pins and push it straight into place.
• Install the two screws using a Phillips #2 screwdriver or Torx T20 screwdriver.
• Torque: No published torque spec; tighten snug only (do not overtighten).

Step 6: Repeat on the other side

• Repeat Steps 1–5 for the other taillight.
• Replace bulbs in pairs for matching brightness.

✅ After Repair

• Turn ignition ON and test: tail lights, brake lights, turn signals, and reverse lights.
• If a bulb doesn’t work, remove the housing again and confirm the bulb is fully seated and the socket is locked.
• Watch for fast turn-signal blinking; it can indicate a bulb isn’t working.
