🔧 Gladiator - Tail Light Bulb Replacement

On your Gladiator, the tail lamp housing comes off from the outside (no interior trim removal). If you have the standard bulb-style tail lamps, you’ll swap the bulb(s) from the back of the housing; if you have factory LED tail lamps, the “bulbs” aren’t serviceable and the whole tail lamp assembly gets replaced.

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

⚠️ Safety & Precautions

• ⚠️ Turn the lights OFF and remove the key before starting.
• ⚠️ Let bulbs cool before touching; they can burn you.
• ⚠️ Don’t touch new glass bulbs with bare fingers; oils can shorten bulb life.
• ⚠️ Support the tail lamp so it doesn’t fall and scratch the paint.
• 🔋 Battery disconnect is not required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the left tail lamp assembly

• Open the tailgate.
• Use a Torx T30 screwdriver to remove the two tail lamp screws on the inside edge of the lamp (visible with the tailgate open).
• Gently pull the tail lamp straight rearward to release the alignment pins.
• If it feels stuck, use a plastic trim removal tool to gently help it pop loose. Pull straight back, not sideways.

Step 2: Disconnect wiring (so you can work comfortably)

• Support the lamp with one hand.
• Unplug the main connector by pressing the lock tab and pulling the connector apart by hand.

Step 3: Replace the “taillight” bulb(s) (bulb-style lamps only)

• Find the bulb socket(s) on the back of the tail lamp.
• Twist the correct socket counterclockwise by hand and pull it out.
• Pull the old bulb straight out of the socket.
• Install the new bulb by pushing it straight into the socket.
• Reinstall the socket into the lamp and twist clockwise by hand until it locks.
• If unsure, match bulb number on old bulb.

Step 4: If equipped with factory LED tail lamps (no serviceable bulbs)

• If you do not see removable bulb sockets and the lamp has a sealed rear cover, it’s an LED unit.
• Use a Torx T30 screwdriver to remove the two screws, pull the lamp out, and use your hands to unplug the connector.
• Install the new tail lamp assembly, plug in the connector, and set the lamp into place.

Step 5: Reinstall the left tail lamp

• Plug the connector back in until it clicks.
• Align the guide pins and push the lamp straight forward into the body.
• Install the two screws using a Torx T30 screwdriver.
• Torque to 3 Nm (27 in-lbs)

Step 6: Repeat on the right side

• Repeat Steps 1–5 for the right tail lamp using the same Torx T30 screwdriver and method.
