• ⚠️ Let the bulbs cool for a few minutes if the lights were recently on.
• ⚠️ Do not touch the glass of a new bulb with bare fingers; skin oil can shorten bulb life.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Trunk and Locate the Rear Lamp Access Area

• Use the trunk release or key fob to open the trunk.
• Use a flashlight to look at the inner trunk liner near the left taillight area.
• You will see carpeted trim covering the back side of the taillight housing.

Step 2: Move the Trunk Trim Aside

• Use a trim clip removal tool to gently lift the plastic trunk liner clips near the taillight area.
• If a clip is stubborn, use a 1/4 inch flat-blade screwdriver to carefully pry under the clip head.
• Use 6 inch needle-nose pliers only if a clip is partly loose and needs a gentle pull.
• Pull the carpeted liner back just enough to reach the bulb sockets.
• Do not crease the trunk liner.

Step 3: Identify the Taillight Bulb Socket

• Use a flashlight to inspect the rear of the lamp assembly.
• The taillight bulb socket is the socket for the red rear running light.
• A bulb socket is the twist-in plastic holder that locks the bulb into the lamp housing.
• On your Altima, turn the socket counterclockwise by hand to unlock it.

Step 4: Remove the Old Left Taillight Bulb

• Use your gloved hand to pull the socket straight out of the taillight housing.
• Remove the old bulb from the socket by pulling it straight out.
• If the bulb is tight, gently wiggle it while pulling by hand.
• Do not use metal tools directly on the bulb glass.

Step 5: Install the New Left Taillight Bulb

• Use nitrile gloves to handle the new bulb.
• Push the new taillight bulb straight into the socket until fully seated.
• Insert the socket back into the lamp housing.
• Turn the socket clockwise by hand until it locks.
• No torque wrench is used here; tighten by hand only until snug.

Step 6: Test the Left Taillight

• Turn the parking lights on from the headlight switch.
• Check that the left taillight illuminates red.
• Turn the lights back off before continuing.
• Testing now avoids reopening trim later.

Step 7: Repeat on the Right Side

• Use the trim clip removal tool to release the right-side trunk liner clips.
• Use the flashlight to locate the right taillight bulb socket.
• Turn the socket counterclockwise by hand and pull it out.
• Pull the old bulb straight out by hand.
• Push the new bulb straight into the socket using nitrile gloves.
• Reinstall the socket and turn it clockwise by hand until locked.

Step 8: Final Light Check

• Turn the parking lights on again.
• Walk behind your Altima and confirm both rear taillights glow evenly.
• Press the brake pedal and confirm the brake lights still work.
• Turn the hazard lights on and confirm rear turn signals still flash normally.

Step 9: Reinstall the Trunk Trim

• Use your hands to move the carpeted liner back into its original position.
• Push the plastic clips back into place by hand.
• If needed, use the 1/4 inch flat-blade screwdriver only to guide the clip, not to force it.
• Make sure the trunk liner sits flat and does not pinch any wiring.
