⚠️ Safety & Precautions

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

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Trunk and Locate the Rear Trim

• Use the flashlight to look at the inside left rear corner of the trunk.
• Find the carpeted trunk side trim directly behind the taillight assembly.
• Repeat this visual check on the right rear corner.
• Take a quick photo first.

Step 2: Remove the Trunk Trim Clips

• Use the trim clip removal tool to gently lift the plastic push clips holding the carpeted trim.
• If a clip has a center pin, use the small flat-head screwdriver to lift the center pin first, then pull the whole clip out.
• Set the clips aside where they will not roll away.
• No torque spec applies because these are push-in trim clips.

Step 3: Pull the Trunk Trim Back

• Use your hands to carefully pull the carpeted trunk trim inward just enough to reach behind the taillight.
• Use the flashlight to identify the bulb sockets.
• The bulb socket is the plastic piece that twists into the back of the lamp housing and holds the bulb.
• Do not sharply fold the carpet trim.

Step 4: Remove the First Taillight Bulb Socket

• Use your gloved hand to grip the taillight bulb socket.
• Turn the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the taillight housing.
• No tool is usually needed for the socket; use only hand pressure.
• Do not pull on wires.

Step 5: Remove the Old Bulb

• Use nitrile gloves and pull the old bulb straight out of the socket if it is a wedge-style bulb.
• If the bulb resists, use the clean microfiber cloth for grip and gently wiggle it while pulling straight out.
• Do not twist hard unless the replacement bulb style clearly has locking pins.

Step 6: Install the New Bulb

• Use nitrile gloves to handle the new taillight bulb.
• Push the new bulb straight into the socket until fully seated.
• Use the clean microfiber cloth to wipe the bulb if you accidentally touched the glass.
• Make sure the bulb sits straight and does not feel loose.

Step 7: Reinstall the Bulb Socket

• Use your gloved hand to insert the socket back into the taillight housing.
• Align the socket tabs with the housing slots.
• Turn the socket clockwise about a quarter turn until it locks.
• No torque spec applies; hand-tight only.

Step 8: Replace the Bulb on the Other Side

• Use the trim clip removal tool to remove the right-side trunk trim clips if needed.
• Pull the carpeted trim back by hand.
• Use your gloved hand to turn the other taillight bulb socket counterclockwise.
• Pull the socket out, remove the old bulb, install the new bulb, then lock the socket back in clockwise.
• Replace both bulbs even if only one failed, because the other is usually close behind.

Step 9: Test the Taillights Before Reinstalling Trim

• Turn the headlight switch to the parking light or headlight position.
• Walk to the rear of your Altima and confirm both taillights are on.
• If one side does not light, turn the lights off and use your gloved hand to remove and reseat that bulb.
• Turn the lights off again after testing.

Step 10: Reinstall the Trunk Trim

• Use your hands to place the carpeted trunk trim back into its original position.
• Use your fingers to push the trim clips back into their holes.
• If the clip has a center pin, push the outer clip body in first, then press the center pin flush.
• No torque spec applies to trunk trim clips.
