⚠️ Safety & Precautions

• ⚠️ Turn the ignition OFF and remove the key before starting.
• ⚠️ Let the bulbs cool if they were just used (they get hot).
• ⚠️ Don’t touch the new bulb’s glass with bare fingers; oils can shorten bulb life.
• ⚠️ Support the tail lamp when loosening nuts so it doesn’t drop or scratch paint.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Expose the back of the tail lamp

• Use a flashlight to locate the trunk-side carpet/liner behind the tail lamp.
• Use a trim clip removal tool to pop out any plastic push clips holding the liner.
• Pull the liner back enough to reach the tail lamp sockets and mounting nuts.

Step 2: Remove the tail lamp mounting nuts

• Put on nitrile gloves and safety glasses.
• Use a 10mm socket, 1/4" drive ratchet, and 6" extension to remove the tail lamp retaining nuts.
• Set the nuts aside where they won’t get lost.
• Tip: Turn slowly—don’t drop nuts into the trunk.

Step 3: Remove the tail lamp assembly

• From outside the car, hold the tail lamp with both hands and pull it straight rearward.
• If it feels stuck, wiggle gently—don’t pry against the paint.

Step 4: Remove the turn signal bulb socket

• Find the turn signal bulb socket on the back of the tail lamp (the socket that aligns with the amber turn signal lens area).
• Twist the socket counterclockwise by hand and pull it out.

Step 5: Replace the bulb

• Pull the old bulb straight out of the socket (it’s a pull-out style on most Altima rear turn signals).
• Install the new rear turn signal bulb (amber) by pushing it straight in until fully seated.
• If you accidentally touch the glass, wipe it with a clean, dry paper towel.

Step 6: Reinstall socket and tail lamp

• Insert the socket into the tail lamp and twist clockwise until it locks.
• Guide the tail lamp back into place, lining up the locating pins.
• Use the 10mm socket, ratchet, and extension to reinstall the nuts.
• Tighten the nuts snugly (do not overtighten—tail lamp studs can crack the housing).

Step 7: Reinstall trunk liner

• Reposition the trunk liner.
• Press the clips back in by hand (use the trim clip removal tool to help align them if needed).

✅ After Repair

• Turn the ignition to ON and test the rear turn signal and hazard lights.
• Verify the bulb flashes at a normal speed (fast flashing usually means a bulb isn’t working or isn’t seated).
• Check that the tail lamp sits flush and doesn’t wobble.
