⚠️ Safety & Precautions

• 🔸Turn the engine off, remove the key, and let all lights cool before touching the bulbs or lamp housing.
• 🔸Set the parking brake and keep the shifter in Park so the vehicle cannot move.
• 🔸Do not touch the glass part of any new bulb with bare fingers; skin oils can shorten bulb life.
• 🔸Battery disconnect is not required for this job, but make sure all exterior lights are switched off.

📋 Before You Begin

• 🔸Park your Equinox on level ground, shift to Park, and set the parking brake.

• 🔸If working outside, avoid direct rain or dust so nothing gets into the open light housing.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the tail lamp screws

• 🔸Open the liftgate to expose the inner edge of the rear tail lights.
• 🔸Locate the two visible screws on the inside edge of the tail light assembly (one high, one low).
• 🔸Put on your mechanic gloves and safety glasses for protection.

Step 2: Remove the tail lamp screws

• 🔸Use the Phillips #2 screwdriver to remove the upper screw holding the tail lamp to the body.
• 🔸Set the screw aside somewhere safe so it doesn’t roll away.
• 🔸Use the Phillips #2 screwdriver to remove the lower screw as well.
• 🔸Again, keep the screw where you can easily find it later. Use a small container for screws

Step 3: Release the tail lamp from the body

• 🔸The outer side of the lamp is still held by plastic pins that push into the body.
• 🔸Place one hand on the outer edge of the tail lamp and the other on the inner edge.
• 🔸Gently pull the lamp straight rearward (toward you) to pop the pins free. Do not pry sideways.
• 🔸If it’s stuck, slide a plastic trim removal tool between the lamp and body and twist gently to help release it. Never use metal here
• 🔸Once loose, support the lamp so it doesn’t dangle by the wiring.

Step 4: Find the rear turn signal bulb socket

• 🔸Turn the lamp over so you can see the back where the wiring and bulb sockets are.
• 🔸The rear turn signal bulb is usually in the middle or lower socket; it will have colored (signal) wires going to it.
• 🔸Note which socket you remove so you don’t mix up brake and reverse bulbs.

Step 5: Remove the bulb socket

• 🔸Grip the correct bulb socket firmly.
• 🔸Rotate the socket about a quarter turn counterclockwise with your hand to unlock it.
• 🔸Pull the socket straight out of the tail lamp housing.

Step 6: Remove the old bulb

• 🔸Hold the socket in one hand and the bulb base (plastic part) in the other.
• 🔸Pull the bulb straight out of the socket. It may be snug; wiggle slightly while pulling.
• 🔸If the bulb is stuck, use the clean lint-free cloth to get better grip and avoid breaking the glass.

Step 7: Prepare the new bulb

• 🔸Take a new rear turn signal bulb from the package, holding it by the base, not the glass.
• 🔸If you accidentally touch the glass, wipe it clean with the clean lint-free cloth.
• 🔸Apply a tiny dab of dielectric grease to the socket contacts to help prevent corrosion. Use very small amount

Step 8: Install the new bulb into the socket

• 🔸Align the bulb’s metal pins or base tabs with the slots in the socket.
• 🔸Push the bulb straight into the socket until it seats firmly.
• 🔸Make sure it is fully seated and does not wobble loosely.

Step 9: Reinstall the bulb socket into the tail lamp

• 🔸Insert the bulb and socket assembly back into the opening in the tail lamp housing.
• 🔸Align the tabs, then rotate the socket clockwise about a quarter turn until it locks in place.
• 🔸Check that the socket is fully seated and cannot be pulled out without twisting.

Step 10: Refit the tail lamp to the vehicle

• 🔸Position the tail lamp back into the body opening, lining up the locating pins on the outer edge with the holes in the body.
• 🔸Press the outer edge of the lamp straight toward the vehicle until the pins snap into place.
• 🔸Keep one hand supporting the lamp so it sits flush with the body panels.

Step 11: Reinstall the tail lamp screws

• 🔸Install the upper screw by hand first to avoid cross-threading.
• 🔸Use the Phillips #2 screwdriver to snug the upper screw. Do not overtighten.
• 🔸Install and snug the lower screw with the Phillips #2 screwdriver as well.
• 🔸For reference, small lamp screws are typically tightened to about 2 Nm (18 in-lbs)—just firm, not forced.

Step 12: Repeat on the other side

• 🔸Perform the same steps on the opposite rear turn signal so both sides have bulbs of the same age and brightness.
• 🔸Replacing in pairs helps maintain consistent light output and color.

✅ After Repair

• 🔸Turn the ignition to ON (engine can be off) and activate the left turn signal; walk to the rear and confirm it flashes normally.
• 🔸Activate the right turn signal and check that side as well.
• 🔸Turn on the hazard lights to make sure both rear turn signals flash together and at normal speed (not very fast).
• 🔸Close the liftgate and verify the lamps still sit flush with the body and do not move when gently pushed.
