The tail-light replacement on a 2020 Chevy Equinox is usually straightforward, but the exact process depends on whether your model uses replaceable bulbs or an LED assembly. In brief, you’ll either swap a bulb or replace the entire tail-light unit.
Assessing your tail light: bulb or LED
Determine whether your Equinox uses a replaceable bulb or an LED module. Look at the tail lamp housing: if you can see a bulb socket inside and replace the bulb without removing the entire unit, you have a traditional bulb. If the tail light is a sealed LED module, you’ll likely need to replace the entire tail-light assembly rather than a single bulb.
What to check by trim
Some trims or regional specifications come with LED tail lights as standard, while others use traditional bulbs for the tail/turn portion. If one side is dark but the other functions normally, you may only need a bulb; if the whole unit is nonfunctional, a full assembly replacement is more likely needed. Always confirm by consulting the owner’s manual or inspecting the current bulb or module.
Tools and parts you'll need
Gather these items before you start to ensure a smooth replacement.
- Replacement bulb(s) or a new tail-light assembly, depending on your setup
- Gloves or a cloth to keep oils off bulbs
- Trim removal tool or flathead screwdriver wrapped in cloth
- Torx or Phillips screwdriver set (if required by your model)
- Socket wrench or ratchet set
- Optional: multimeter (to test for power if a light still won’t work after replacement)
Having the right tools on hand helps ensure a safe, efficient replacement and reduces the risk of damaging panels or wiring.
Replacing an incandescent tail light bulb
Bulb replacement steps
- Park the vehicle, set the parking brake, and turn off the ignition. Open the hatch to access the tail-light area.
- If needed, disconnect the negative battery terminal to minimize any risk of short circuits (optional but recommended for safety).
- Remove interior trunk trim or the access panel behind the tail light to expose the rear of the lamp housing.
- Locate and remove the screws or bolts securing the tail-light assembly, or simply twist the bulb socket counterclockwise to release it from the housing.
- Carefully pull the bulb socket out and twist the bulb counterclockwise to release it from the socket.
- Inspect the bulb and replace it with a new one of the correct type and rating. Avoid touching the bulb glass with your bare fingers; use a clean cloth or gloves.
- Reinstall the bulb into the socket, then reinsert the socket back into the housing. Reattach the tail-light assembly or cover, reseat the interior trim, and secure all fasteners.
- Reconnect the battery (if you disconnected it) and test the tail light, brake light, and turn signal functions before closing the hatch.
With the bulb replaced, the tail light should function normally. If it still does not light, recheck the bulb seating, wiring, and fuses, or consider professional service.
Replacing an LED tail light assembly
LED tail-light assembly replacement steps
- Identify that your tail light is an LED assembly by inspecting for a sealed module—LED units are typically not user-serviceable at the bulb level.
- Park the vehicle, set the parking brake, and open the hatch. Remove interior trunk panels to access the back of the tail-light housing.
- Disconnect the wiring harness connected to the LED tail light module. Depending on the model, you may need to turn a securing screw or release a locking tab.
- Remove the mounting screws or bolts that hold the tail-light assembly in place, then carefully pull the unit away from the vehicle body.
- Align the replacement LED tail-light assembly with mounting points and reconnect the wiring harness. Reinstall any screws or fasteners and reattach interior trim.
- Test the new tail light to ensure the tail, brake, and turn signal functions operate correctly. If a module is faulty, the entire assembly replacement is typically required.
LED tail lights may require a full assembly replacement if individual LEDs fail. Always verify compatibility with your specific trim and VIN, and follow the dealer or supplier instructions for proper installation.
Testing the new tail light and safety tips
After installation, verify all functions across both sides and ensure the lens is clean and free of moisture. Proper testing helps prevent sent-off-by-error issues on the road.
- Turn on the headlights to confirm the tail lights illuminate. Observe both the tail light and brake light functions from a distance.
- Engage the turn signals to confirm both direction indicators operate correctly.
- Check for any condensation or moisture inside the lens; reseal if necessary to prevent corrosion.
- If anything remains nonfunctional, recheck connections, fuses, and the specific bulb or module compatibility.
Once all functions are verified, you’re done. If you’re uncomfortable performing the replacement, a professional technician can handle bulb changes or assembly replacements quickly and safely.
Common issues and troubleshooting
If the tail light doesn’t light after replacement, consider these possibilities: a blown fuse, a faulty wiring harness, a corroded connector, or a defective LED module. Always consult the owner’s manual for fuse locations and recommended amperage, and check for any recalls or service bulletins related to tail lights for your year and trim.
Summary
For a 2020 Chevy Equinox, tail-light work falls into two paths: replace a bulbed incandescent bulb or swap the entire LED tail-light assembly. Determine the type by inspecting the back of the tail light and consult the manual if unsure. Gather the right tools, follow the step-by-step procedures for bulbs or assemblies, and test the lights thoroughly before driving. When in doubt, seek professional assistance to ensure safety and proper function.
