🔧 Taillight Bulbs - Replacement

This job replaces both rear taillight bulbs on your Equinox. On this vehicle, the bulb sockets are typically accessed from inside the cargo area, so you do not need to remove the whole lamp assembly unless the lamp is LED-only. If your rear lamps are not lighting at all, this is the first thing to check before replacing the entire housing.

Difficulty Level: Beginner | Estimated Time: 0.5-1 hour

• Use care around plastic trim so the clips do not break.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the rear lamp service area

• Open the liftgate.
• Use the trim panel tool to gently pry off the rear side cargo trim access cover behind the taillight area.
• Work slowly to avoid breaking clips.

Step 2: Remove the bulb socket

• Locate the bulb socket on the back of the taillight housing.
• Use your hand to turn the socket counterclockwise and pull it straight out.
• If it is tight, use a small flat-blade screwdriver carefully to help release the tab, but do not force it.

Step 3: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new bulb by pressing it straight into the socket until fully seated.
• Make sure the bulb is locked in straight and not crooked.

Step 4: Reinstall the socket

• Line up the socket with the housing.
• Use your hand to turn it clockwise until it locks in place.
• Do not overtighten.

Step 5: Repeat on the other side

• Perform the same steps for the opposite taillight bulb.
• Replace both bulbs together so the light output matches side to side.

Step 6: Reinstall the trim cover

• Use your hands to press the cargo trim access cover back into place.
• Make sure all clips are fully seated.
