🔧 Altima - Front Turn Signal Bulb Replacement

You’ll remove the old front turn signal bulb(s) and install new amber bulbs. This fixes a burned-out signal and prevents fast “hyperflash” blinking that happens when a bulb is out.

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

⚠️ Safety & Precautions

• 🧤 Work on a level surface and let the headlight area cool first.
• 🧼 Do not touch the new bulb glass with bare fingers (skin oils can shorten bulb life); hold it by the base.
• 🧯 If you raise the car, support it with jack stands before reaching into the wheel well.
• 🔦 Keep the key off and lights off while unplugging any bulb sockets.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which front bulb is out

• Turn the ignition to ON and use the turn signal stalk to test left and right.
• Turn the hazards ON to check both sides at once, then turn everything OFF.

Step 2: Choose your access method

• Most Altima front turn signal bulbs are accessed from behind the headlamp through the wheel well liner.
• If you can clearly reach the turn signal socket from the engine bay behind the headlamp, you may not need to lift the car.
• Wheel-well access is usually easiest.

Step 3: Lift the front corner (wheel-well method)

• Use a 21mm lug nut socket and breaker bar (1/2") to loosen the lug nuts (do not remove yet).
• Use a floor jack (rated 2-ton minimum) to lift the front corner at a safe jacking point.
• Set the car onto jack stands (pair, rated 2-ton minimum) before working.
• Remove the wheel using the 21mm lug nut socket.

Step 4: Pull back the front fender liner

• Use a trim clip removal tool to remove the plastic push clips along the front portion of the liner.
• If equipped with screws, remove them with a Phillips screwdriver #2 or a 10mm socket and ratchet (1/4" or 3/8").
• Pull the liner back enough to reach behind the headlamp.
• A trim clip tool is a small forked pry tool that pops plastic clips out without breaking them.

Step 5: Remove the turn signal bulb socket

• Use a flashlight to locate the turn signal socket on the back of the headlamp.
• Grip the socket and rotate it counterclockwise about 1/4 turn by hand, then pull it straight out.
• If space is tight, reposition the liner more rather than forcing the socket.

Step 6: Replace the bulb

• Wear nitrile gloves.
• Pull the old bulb straight out of the socket.
• Push the new front turn signal bulb (amber) straight into the socket until fully seated.
• If you touched the glass, wipe it clean.

Step 7: Reinstall the socket and secure the liner

• Insert the socket back into the headlamp and rotate clockwise to lock by hand.
• Reposition the liner and reinstall clips using the trim clip removal tool.
• If you removed screws/bolts, reinstall using a Phillips screwdriver #2 or 10mm socket and ratchet (1/4" or 3/8").

Step 8: Reinstall the wheel (if removed)

• Install lug nuts by hand first.
• Lower the car using the floor jack (rated 2-ton minimum) and remove the jack stands (pair, rated 2-ton minimum).
• Tighten lug nuts in a star pattern using the 21mm lug nut socket.
• Torque to 113 Nm (83 ft-lbs).
