🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which bulb is out

• Turn the ignition to ON and use the turn signal stalk to test left and right signals.
• Turn ignition OFF when you’ve confirmed which side needs the bulb.
• Fast blinking usually means a bulb is out.

Step 2: Access the rear lamp area inside the trunk

• Open the trunk and locate the trunk liner behind the tail lamp on the side you’re working on.
• Use a trim clip removal tool to pop out any plastic push-clips holding the liner.
• If needed, carefully help the clip center up with a small flathead screwdriver, then remove the clip.
• Fold the trunk liner back to expose the tail lamp bulb sockets.

Step 3: Remove the rear turn signal bulb socket

• Identify the turn signal socket (it’s the socket that aligns with the amber turn signal portion of the lamp).
• Unplug the connector by pressing the tab and pulling straight back.
• Twist the bulb socket counterclockwise by hand and pull it out.
• A “socket” is the plastic holder the bulb locks into.

Step 4: Replace the bulb

• Wear nitrile gloves and pull the old bulb straight out of the socket.
• Push the new 7440A / amber bulb straight into the socket until fully seated.

Step 5: Reinstall the socket and reassemble trunk trim

• Reinsert the socket into the housing and twist clockwise until it locks.
• Reconnect the electrical connector until it clicks.
• Reposition the trunk liner and reinstall the clips by pressing them in by hand.

Step 6: If you removed any tail lamp mounting nuts (only if needed)

• If you had to loosen/remove tail lamp nuts for access, reinstall them using a 10mm socket and 1/4" ratchet.
• Tighten with a torque wrench (in-lb): Torque to 5 N·m (44 in-lb).
• Snug only—overtightening can crack the lamp.
