🔧 Taillight Bulbs - Bulb Replacement
Replacing both rear taillight bulbs on your Corolla is a quick job. On this model, the rear lamp bulb is accessed from inside the trunk, so you do not need to remove the whole taillight housing.

- Let the bulbs cool down first if the lights were on recently; bulbs get very hot.
- Use gloves or a clean cloth when handling new halogen bulbs. Oil from your fingers can shorten bulb life.
- Keep the trunk lid supported and make sure tools do not scratch the paint.
- Battery disconnect is not required for this repair.

🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the trunk access area
- Open the trunk and locate the small access covers behind each taillight assembly.
- Use a trim clip removal tool to pop out the side trim retainers if needed for better access.
Step 2: Remove the bulb access cover
- Pull off the rear lamp access cover by hand.
- If a fastener is in the way, use a 10mm socket with a 1/4-inch ratchet and extension bar to move the trim panel as needed.
Step 3: Remove the bulb socket
- Twist the bulb socket counterclockwise and pull it straight out of the taillight housing.
- Do not force it.
Step 4: Replace the bulb
- Press the old bulb in slightly, twist it counterclockwise, and remove it from the socket.
- Install the new rear stop/tail bulb by pushing it in and twisting it clockwise until it locks.
- Use gloves while handling the new bulb.
Step 5: Reinstall the socket
- Align the socket tabs with the housing and twist it clockwise to lock it in place.
- Make sure the socket sits fully seated and the seal is not pinched.
Step 6: Test the new bulbs
- Turn on the parking lights and then press the brake pedal to confirm both rear bulbs work.
- If one side does not light, remove the socket again and check bulb orientation.
Step 7: Reassemble the trunk trim
- Reinstall the access cover and any trim clips you removed.
- Make sure everything is secure and the trunk closes normally.
✅ After Repair
- Check tail lights, brake lights, and turn signals one more time.
- Look at the rear of the car in a dark area to confirm both sides are equally bright.
- If a bulb does not work, recheck the socket and bulb fitment.
