• 🧤 Wear gloves—bulbs can be hot and can break if squeezed.
• ⚠️ Don’t touch the new bulb’s glass with bare fingers (skin oil can shorten bulb life).
• 🔌 Battery disconnect is not required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which rear lamp section is out

• Turn on the hazard lights and walk around the rear.
• Confirm the rear turn signal section that’s not flashing (left or right).
• Turn hazards OFF and switch ignition OFF.

Step 2: Remove the rear combination lamp fasteners

• At the inside edge of the tail lamp (hatch open), use a trim removal tool (plastic) to pop off the small access cover(s) if equipped.
• Use a 10mm socket, 3" extension (1/4" drive), and 1/4" drive ratchet to remove the tail lamp retaining nuts/bolts.
• Set the fasteners aside where they won’t fall into the trim.

Step 3: Remove the tail lamp assembly

• Hold the lamp with both hands and pull it straight rearward (away from the body) to release the locating pins/clips.
• If it feels stuck, use a trim removal tool (plastic) to gently help it break free—do not pry hard on the painted body.
• Tip: Pull straight back, not outward.

Step 4: Remove the turn signal bulb socket

• Find the turn signal bulb socket on the back of the lamp (the socket that lines up with the amber turn signal section).
• Rotate the socket counterclockwise by hand to unlock it, then pull it out.
• If it’s tight, use a nitrile gloves grip and a flashlight to see the lock tabs.

Step 5: Replace the bulb

• Pull the old bulb straight out of the socket by hand (no twisting on most wedge-base bulbs).
• Install the new bulb by pushing it straight in until fully seated.
• Use the flashlight to read the bulb number on the old bulb and match it when buying the replacement.
• If the bulb is glass, handle it with nitrile gloves.

Step 6: Quick function test before reassembly

• Reinsert the socket into the lamp and twist clockwise to lock.
• Turn the hazards ON and confirm the new bulb flashes normally.
• Turn hazards OFF.

Step 7: Reinstall the tail lamp assembly

• Line up the locating pins/clips with the body holes and push the lamp straight forward until it seats flush.
• Reinstall the retaining nuts/bolts using a 10mm socket, 3" extension (1/4" drive), and 1/4" drive ratchet.
• Torque to 5.4 Nm (48 in-lbs) using a torque wrench (inch-pound) (specialty).
• Reinstall any access covers using the trim removal tool (plastic) if needed.

✅ After Repair

• Turn on hazards and confirm both rear turn signals flash at a normal speed.
• Check the brake lights and tail lights while you’re there (easy to verify now).
• If the turn signal still “hyper-flashes” quickly, double-check the bulb is fully seated and the correct type.
