• 🔸 Let bulbs cool first; they can be hot right after use.
• 🔸 Don’t touch new bulb glass with bare fingers; oils can shorten bulb life.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the taillight housing (one side)

• Use a Torx T15 screwdriver to remove the two taillight mounting screws (accessible with the tailgate open).
• Hold the housing with your other hand so it doesn’t drop or scratch the paint.
• Pull the taillight housing straight rearward to release the locator pins. If it’s stuck, use a trim/panel removal tool to gently help it pop free. Pull straight back, not sideways.

Step 2: Remove the bulb sockets

• Locate the two twist-lock bulb sockets on the back of the housing.
• Use your hand (or a nitrile glove for grip) to rotate each socket about 1/4 turn counterclockwise, then pull it out.
• The larger red-lens bulb socket is typically the stop/turn/tail (3157); the clear-lens bulb socket is the reverse (3156).

Step 3: Replace the bulbs

• Pull the old bulb straight out of the socket.
• Install the new bulb by pushing it straight into the socket until fully seated.
• If you accidentally touch the glass, wipe it with a clean, dry cloth before installing.

Step 4: Test the lights before reassembly

• Reinsert each socket into the housing and twist clockwise to lock by hand.
• Turn on the parking lights to verify the tail lights illuminate.
• Press the brake pedal (have a helper watch) to verify brake lights.
• Turn on the hazard flashers to verify turn signals.
• With the clutch in and parking brake set, shift to reverse briefly (key on) to verify reverse lights. Use a flashlight if needed to see clearly in daylight.

Step 5: Reinstall the taillight housing

• Align the housing locator pins with the body grommets, then push the housing straight in until it seats.
• Install the two screws using a Torx T15 screwdriver.
• Torque to 2 Nm (18 in-lbs)

Step 6: Repeat on the other side

• Repeat Steps 1–5 for the opposite taillight so bulbs are replaced in pairs.

✅ After Repair

• Re-check: tail lights, brake lights, hazards/turn signals, and reverse lights.
• Make sure both housings sit flush and don’t wiggle.
• If a new bulb doesn’t work, re-check the socket is fully twisted/locked and the bulb is fully seated.
