You'll need the following tools for this repair:
- Trim removal tool
- Phillips #2 screwdriver
- 10mm socket
- 1/4" ratchet

🔩 Required Parts
HowToo sells all the parts you need for this repair:
- Rear taillight bulbs (left and right) - Qty: 2
Assumption: you’re replacing the main taillight/brake bulbs on both sides; match the bulb type by reading the number on your old bulb or using your owner’s manual.
đź“‹ Before You Begin
- Park on level ground and set the parking brake.
- Open the trunk and remove anything that blocks access to the side trim.
- Put on nitrile gloves (thin gloves that keep skin oil off bulbs).
- Have a flashlight ready so you can see the bulb sockets clearly.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Access the taillight service covers
- Open the trunk.
- On the left trunk liner, locate the small access door/cover behind the taillight area.
- Use a trim removal tool to pop open the access cover (work gently to avoid breaking clips).
- Repeat on the right side for the other taillight.
Step 2: Remove the bulb socket
- Look for the bulb socket going into the back of the taillight housing.
- Grip the socket firmly and turn it counterclockwise about 1/4 turn.
- Pull the socket straight out.
- If tight, wiggle gently—don’t yank wires.
Step 3: Remove the old bulb
- Pull the old bulb straight out of the socket.
- If it’s stuck, use a clean shop towel for grip and pull straight (don’t twist unless it’s a twist-lock style).
- Use your flashlight and read the bulb number printed on the base to ensure you have the correct replacement.
Step 4: Install the new bulb
- With nitrile gloves on, push the new bulb straight into the socket until fully seated.
- If you accidentally touch the glass, wipe it with a clean shop towel before installing.
Step 5: Reinstall the socket and close the access cover
- Align the socket tabs with the housing and insert the socket fully.
- Turn the socket clockwise about 1/4 turn until it locks.
- Snap the trunk access cover back into place by hand.
- Repeat Steps 2–5 on the other side to replace the second taillight bulb.
Step 6: If your bulb isn’t accessible (rare case)
- If you can’t reach the socket through the access door, the trunk liner may need to be pulled back further.
- Use a trim removal tool to remove a few liner clips, then fold the liner back for access.
- If a small fastener is present, remove with a Phillips #2 screwdriver or 10mm socket as needed.
âś… After Repair
- Turn the headlight switch ON and confirm both rear taillights illuminate.
- Press the brake pedal (or have someone help) and confirm both brake lights brighten.
- Turn on hazards and verify both rear turn signals flash normally (fast flashing usually means a bulb issue).
- Make sure both trunk access covers are fully clipped in so the liner doesn’t rattle.
