⚠️ Safety & Precautions

• 🛑 Park on level ground, shift to Park, and set the parking brake.
• 🛑 Turn the ignition off and remove the key before working on the lights.
• 🛑 Let someone know you’re working around the rear of the vehicle so they don’t move it accidentally.
• 🛑 Avoid touching glass bulbs with bare fingers; skin oils can shorten bulb life.

📋 Before You Begin

• Open the rear liftgate fully so you can see the side taillights.
• Make sure the vehicle is off and in Park with the parking brake set.
• Lay a towel or blanket on the bumper to protect paint from dropped tools or the lamp housing.
• If you have a helper, ask them to be ready later to press the brake pedal so you can confirm the lights work.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the taillight screws

• Open the liftgate so you can see the inner edge of the taillight where it meets the body.
• Locate the two black Phillips screws on the inner vertical edge of the taillight (one near the top, one near the bottom).
• Use the Phillips #2 screwdriver to loosen and remove both screws. Set them aside in a small tray so they don’t roll away.
• Torque when reinstalling: Tighten screws gently to about 3 Nm (27 in-lbs) — just snug, don’t over-tighten.

Step 2: Release and remove the taillight housing

• The taillight is still held by alignment pins that push into clips in the body.
• Place one hand on the outer edge of the taillight and the other on the inner edge.
• Pull the taillight straight rearward away from the vehicle. Use a gentle wiggling motion.
• If it feels stuck, use the trim removal tool between the inner edge of the taillight and body and gently pry straight back. Do not pry sideways.
• Once the pins release, carefully pull the housing back just enough to access the wiring and bulb sockets.

Step 3: Identify the bulb sockets

• On the back of the taillight housing you’ll see round plastic bulb sockets with wires going to them.
• Typically, the upper socket is the main tail/brake/turn bulb and the lower socket is the reverse bulb.
• Make a quick note or photo of which socket is which before you remove them. Photos help beginners a lot.

Step 4: Remove the bulb sockets

• Choose one socket at a time so you don’t mix them up.
• Grasp the first socket firmly and rotate it about a quarter turn counterclockwise.
• Pull the socket straight out of the taillight housing.
• Repeat for the other socket if you’re replacing both bulbs.

Step 5: Remove the old bulbs

• For each socket, gently push the bulb inward (if it’s a push-and-turn style) and twist it counterclockwise, or simply pull it straight out if it’s a push-in type.
• If it’s tight, use the small flathead screwdriver 4mm very gently at the base of the bulb to help pry, but do not damage the socket.
• Discard old bulbs; don’t reuse them.

Step 6: Install the new bulbs

• Put on your clean gloves so you don’t touch the new bulb glass with bare fingers.
• Lightly apply a tiny dab of dielectric grease to the metal contacts on the bulb base. This helps prevent corrosion.
• Insert the new bulb into the socket:
  • Push-in type: line up the pins and push straight in until it clicks or feels firmly seated.
  • Push-and-turn type: insert, push in gently, then rotate clockwise to lock.
• Repeat for the other bulb in the second socket.

Step 7: Reinstall bulb sockets into taillight housing

• Line up the tabs on the socket with the slots in the taillight housing opening.
• Insert the socket fully into the housing opening.
• Twist the socket clockwise about a quarter turn with your hand until it stops and feels snug. Hand-tight only.
• Repeat for the other socket.

Step 8: Test the bulbs before refitting the housing

• Let the taillight housing hang supported by one hand or rest it gently on the towel-covered bumper so there is no strain on the wires.
• Turn the ignition to ON (engine can stay off).
• Turn on the parking lights/headlights and confirm the tail lights are glowing.
• Have a helper press the brake pedal: confirm the brake portion lights brightly.
• Turn on the left and right turn signals: confirm each side flashes correctly.
• Shift briefly into Reverse (with parking brake firmly set and foot on brake) to check the reverse light, then back to Park.
• Turn ignition off again before continuing.

Step 9: Reinstall the taillight housing

• Align the alignment pins on the back of the taillight with the holes/clips in the body.
• Hold the housing straight and push it forward into place until you feel the pins snap into the clips.
• Make sure the edges sit flush with the body and the liftgate opening.

Step 10: Reinstall and tighten the screws

• Reinstall the two Phillips screws using the Phillips #2 screwdriver.
• Tighten them gently until snug; do not overtighten or you can crack the plastic.
• Torque: about 3 Nm (27 in-lbs) — this is “firm snug” by hand.

Step 11: Repeat for the other side

• Repeat Steps 1–10 for the taillight on the other side of your Equinox.
• Always replace bulbs in pairs for even brightness.

  • Both tail lights (with parking lights on).
  • Both brake lights.
  • Both rear turn signals.
  • Both reverse lights (with someone holding the brake and briefly in Reverse).
• Check that the taillight housings sit evenly and there are no gaps.
• Make sure there are no “bulb out” warnings on your dash (if equipped).
• Clean any fingerprints or smudges off the lenses with a soft cloth.
