🔧 Equinox - Headlight Bulb Replacement (Both Sides)

You’ll be replacing the low-beam and high-beam bulbs on both sides of your Equinox by accessing the back of each headlight from under the hood. Most of the work is gently moving parts out of the way and twisting the bulb holders out.

Difficulty Level: Beginner | Estimated Time: 1-1.5 hours

⚠️ Safety & Precautions

• ⚠️ Turn the engine off, remove the key, and let everything cool so you don’t burn your hands.
• ⚠️ Turn the headlight switch OFF so the lights cannot come on while you work.
• ⚠️ Do not touch the glass part of the new bulb with bare fingers; oil can make it burn out early.
• ⚠️ Work in a well-lit area and keep loose clothing or jewelry away from moving parts.
• ⚠️ Battery disconnect is not required, but you may disconnect the negative terminal for extra safety if you wish.

📋 Before You Begin

• Park the Equinox on level ground, set the parking brake, and switch headlights OFF.
• Open the hood using the interior hood release, then the safety latch at the front of the vehicle.
• Make sure you have all bulbs on hand before starting so you can finish in one go.
• If you want extra safety, disconnect the negative battery cable with the 10mm socket, but it is not required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify low and high beam bulb locations

• Open the hood and stand in front of the Equinox.
• Each headlight has two bulb positions on the back: the inner one is the high beam (9005), the outer one closer to the fender is the low beam (H11).
• Look for round plastic bulb holders with wiring connectors going to them.

Step 2: Gain access on the driver side (if tight)

• The driver side can be a bit tight because of nearby components.
• If needed, use the 10mm socket and ratchet to remove one or two small bolts that hold any plastic cover or coolant reservoir bracket that blocks access to the bulb. Move the part gently aside without disconnecting hoses.
• Torque when reinstalling: Tighten to 8 Nm (71 in-lbs) using the 10mm socket.
• Only move parts enough to reach the bulb.

Step 3: Unplug the low beam bulb connector

• Pick one side to start (passenger side is usually easier).
• Find the outer bulb holder (low beam H11) on the back of the headlight.
• Press the small locking tab on the electrical connector with your finger or use the flathead screwdriver gently to lift it if it’s stuck.
• Pull the connector straight back away from the bulb. If it’s tight, gently wiggle while pulling, or use needle-nose pliers carefully on the plastic plug, not the wires.

Step 4: Remove the low beam bulb

• With the connector off, grab the plastic base of the H11 bulb.
• Turn the bulb holder about 1/4 turn counterclockwise by hand to unlock it.
• Pull the bulb straight out of the headlight housing.
• Do not force; check you turned it fully.

Step 5: Install the new low beam bulb

• Put on clean gloves. Do not touch the glass part of the new H11 bulb; hold it by the plastic base.
• If you accidentally touch the glass, wipe it with a clean alcohol wipe and let it dry.
• Match the tabs on the bulb base with the slots in the headlight opening.
• Insert the bulb into the hole and turn it about 1/4 turn clockwise until it stops. This locks it in place.
• Apply a tiny dab of dielectric grease inside the electrical connector opening (optional but helps prevent corrosion).
• Push the electrical connector back onto the bulb base until it clicks.

Step 6: Replace the high beam bulb on the same side

• Find the inner bulb holder (high beam 9005) on the same headlight.
• Press the connector tab and unplug it using your fingers or the flathead screwdriver gently if tight.
• Turn the 9005 bulb holder 1/4 turn counterclockwise and pull it straight out.
• With gloves on, insert the new 9005 bulb, align the tabs, and turn 1/4 turn clockwise to lock.
• Add a tiny dab of dielectric grease to the connector, then plug it on until it clicks.

Step 7: Repeat for the other side

• Repeat Steps 3–6 for the other headlight: low beam H11 first, then high beam 9005.
• On the driver side, if you moved any brackets or covers earlier, make sure you can still reach the bulbs safely.
• Reinstall any brackets you removed using the 10mm socket and ratchet.
• Torque those bolts: 8 Nm (71 in-lbs) with the 10mm socket.

Step 8: Check wiring and seating

• Look at each bulb from the back: the bulb base should be fully seated and not crooked.
• Make sure each connector is fully pushed in and locked; gently tug each plug with your fingers to confirm it’s secure.
• Use a shop towel to wipe off any fingerprints or smudges around the headlight area.

Step 9: Test the headlights

• Close the hood partway (but not latched) and stand where you can see the front of the Equinox safely.
• Turn the ignition to ON (engine can stay off).
• Turn on the low beams: both low beams should light evenly.
• Switch to high beams: both high beams should light. Check the high-beam indicator on the dash.
• If one does not light, turn everything OFF and recheck that bulb’s connector and seating position.

✅ After Repair

• 🔍 With lights on, stand in front of a wall at night to confirm both low and high beams are similar brightness and height.
• 🚗 Take a short drive in the evening to confirm the light pattern looks normal and not aimed too high or low.
• 🔧 If the beam looks off (too high/low on one side), you may need a headlight aim adjustment later using the headlight adjuster screws.
• 🧹 Put away tools and keep spare bulbs (if any) in your glove box as backups.
