- 🧯 Do not use metal tools on electrical connectors with the lights on to avoid short circuits.
- 🪟 Work in a well-lit area and keep the trunk lid supported and fully open.
- 🔌 Battery disconnect is not required for this job if the ignition is OFF.

📋 Before You Begin
- 🚗 Park the Camry on level ground, shift to Park, and set the parking brake.
- 🧳 Empty large items from the trunk so you have space to work.
- 💡 Turn the hazard lights ON briefly to confirm which bulb is out, then turn them OFF again.
- 🧴 If you touch the glass part of a new bulb, wipe it with a clean cloth so no skin oil stays on it.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the trunk and locate the access panel
- Use your hands to open the trunk fully and make sure it stays up securely.
- Use the work light or flashlight to look at the inside wall of the trunk, behind each tail light area.
- You will see a small fabric or plastic trim cover near the tail light on each side; this is the access panel for the bulbs.
Step 2: Remove the trunk trim access cover
- Use the trim removal tool (plastic) to gently pry the edge of the access cover away from the trunk side lining.
- If the cover has a small plastic clip, use the flathead screwdriver (small) to gently lift the center of the clip, then pull the clip out with your fingers.
- Set the cover and any clips aside somewhere safe so they don’t fall into the trunk well.
- Pull slowly so clips don’t snap.
Step 3: Find the rear turn signal bulb socket
- Use the work light or flashlight to look inside the opening you just made.
- You will see several bulb sockets on the back of the tail light; the rear turn signal on your Camry is usually the upper outer bulb and has an amber (orange) appearance when lit.
- To confirm the correct socket, note that the turn signal socket is typically larger than the small marker light socket and points toward the outer side of the car.
Step 4: Remove the rear turn signal bulb socket
- Put on your mechanic gloves to protect your hands.
- Grip the bulb socket firmly with your hand.
- Turn the socket about a quarter turn counterclockwise with your hand until it feels free, then pull it straight out of the tail light housing.
- Do not pull on the wires.
Step 5: Remove the old bulb
- Hold the socket in one hand and the bulb glass in the other.
- This style is a “wedge” bulb, meaning it simply pushes in and pulls out without a twist.
- Pull the old bulb straight out of the socket with your fingers; if it is stuck, gently wiggle it while pulling.
- Dispose of the old bulb safely so it doesn’t break in the trunk.
Step 6: Install the new bulb
- Pick up the new rear turn signal bulb (7440 amber) by the base if possible; avoid touching the glass.
- Align the metal contacts on the bulb base with the slot in the socket.
- Push the new bulb straight into the socket using your fingers until it is fully seated and does not wobble.
- If it feels loose, push a bit harder.
Step 7: Test the new bulb before reassembly
- Let the bulb and socket hang gently where they are, making sure they are not touching any fabric.
- Turn the ignition to ON (engine can stay off) and switch on the left or right turn signal for the side you are working on.
- Go to the rear of the Camry and check that the new bulb is flashing brightly and at the same speed as the other side.
- Turn the ignition OFF and the signal OFF once you confirm it works.
Step 8: Reinstall the bulb socket into the tail light
- Carefully guide the bulb and socket back into the hole in the tail light housing.
- Align the tabs on the socket with the slots in the housing.
- Turn the socket clockwise by hand about a quarter turn until it stops and feels snug.
- It should sit flat and not move.
Step 9: Reinstall the trunk trim access cover
- Align the access cover with the opening in the trunk trim.
- Use your hands to push the cover back into place until it clicks in.
- If you removed any clips, push them back into their holes by hand; if they are two-piece clips, push the outer part in first, then press the center pin down with your thumb.
- Use the trim removal tool (plastic) or your fingers to make sure the trunk lining sits flat again.
Step 10: Repeat on the other side (recommended)
- For even brightness and to avoid the other side failing soon, repeat the same steps on the other rear turn signal.
- Use the same trim removal tool (plastic), flathead screwdriver (small), and work light or flashlight as needed.
- Replacing in pairs keeps lighting consistent.
✅ After Repair
- 🔄 Turn on the left and right turn signals and the hazard lights to confirm all rear turn signals flash properly.
- 🚗 In a safe area, have a helper stand behind the Camry while you use both signals and brakes to confirm everything looks normal.
- 🧹 Make sure no tools or old bulbs are left in the trunk, and that all trim panels are secure and not loose or rattling.
