🔧 Altima - Taillight Bulb Replacement

On your Altima, the rear lamp bulbs are serviced from inside the trunk—no need to remove the whole taillight for most bulb swaps. You’ll open the trunk trim access, twist the bulb socket out, and swap the bulb.

Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

⚠️ Safety & Precautions

• ⚠️ Turn the lights OFF and remove the key before starting.
• ⚠️ Let bulbs cool first; they can get hot.
• ⚠️ Don’t touch the glass part of a bulb with bare fingers; skin oil can shorten bulb life.
• ⚠️ Support the trunk trim so clips don’t snap.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which bulb you’re replacing

• Turn the parking lights ON to check tail/running lights, then OFF.
• Have a helper press the brake pedal to confirm brake lights.
• If unsure, we’ll replace the stop/tail bulbs first.

Step 2: Access the bulb socket from the trunk

• Open the trunk and go to the side you’re replacing.
• Use a trim clip removal tool to gently pop the trunk liner clips as needed.
• If equipped with a small access cover, remove it by hand or with a Phillips #2 screwdriver.
• Go slow—plastic clips break easily.

Step 3: Remove the bulb socket

• Find the socket that matches the failed light (usually the stop/tail socket is one of the larger sockets).
• Grip the socket and rotate it counterclockwise about 1/4 turn, then pull it straight out.
• Use a flashlight to confirm the socket tabs line up with the housing slots.

Step 4: Replace the bulb

• Put on nitrile gloves.
• Pull the old bulb straight out of the socket.
• Push the new bulb straight into the socket until fully seated.
• Don’t force it—recheck alignment.

Step 5: Reinstall the socket and recheck operation

• Insert the socket back into the taillight housing.
• Rotate clockwise to lock.
• Turn the lights ON and test the function again (tail/brake/turn as applicable).

Step 6: Repeat on the other side

• Move to the opposite trunk side and repeat Steps 2–5.
• Replace bulbs in pairs for equal brightness.

Step 7: Reinstall trunk trim

• Reposition the trunk liner.
• Press clips back in by hand; if needed, use a Phillips #2 screwdriver to reinstall any screws.

✅ After Repair

Quick question so I match the exact bulbs: Are you replacing the brake/tail (red) bulbs, the turn signal bulbs, or the reverse (white) bulbs?
