🔧 Patriot - Taillight Bulb Replacement

You’ll remove each rear lamp housing, twist out the bulb socket, and swap in new bulbs. This is a quick job, but taking care with the plastic lamp pins and not touching the glass helps prevent broken parts and early bulb failure.

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

⚠️ Safety & Precautions

• ⚠️ Turn ignition off and remove the key before starting.
• ⚠️ Let bulbs cool first; they can burn you right after use.
• ⚠️ Don’t touch the new bulb glass with bare fingers; skin oil can shorten bulb life.
• ⚠️ Support the lamp housing as you pull it out so you don’t crack the lens or bend the locating pins.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the left taillamp screws

• Open the liftgate.
• Locate the two Phillips screws on the inboard edge of the left taillamp (near the liftgate opening).
• Use a small flashlight if needed to see the screw heads clearly.

Step 2: Remove the left taillamp housing

• Use a Phillips #2 screwdriver to remove the two screws.
• Pull the taillamp housing straight rearward to release it from the body pins (it may “pop” free).
• If it feels stuck, use a trim clip removal tool gently at the edge to help start it moving.
• Pull straight back to avoid breaking pins.

Step 3: Remove the bulb socket

• Identify the main taillight bulb socket (usually the larger socket for the stop/turn/taillamp bulb).
• Twist the socket counterclockwise about 1/4 turn by hand, then pull it out of the housing.
• Wear nitrile gloves to keep oils off the bulb.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket.
• Push the new 3157 bulb straight into the socket until fully seated.
• If you accidentally touch the glass, wipe it clean with a lint-free cloth (with gloves on).

Step 5: Reinstall the socket and lamp (left side)

• Insert the socket back into the housing and twist clockwise to lock.
• Line up the lamp housing locating pins with the body holes and press the housing straight in until fully seated.
• Reinstall the two screws using a Phillips #2 screwdriver.
• Torque to 2 Nm (18 in-lbs) (snug only; do not overtighten plastic).

Step 6: Repeat on the right side

• Repeat Steps 1–5 on the right taillamp assembly using the Phillips #2 screwdriver, trim clip removal tool, and nitrile gloves.

✅ After Repair

• Press the brake pedal (or have a helper press it) and confirm both brake lights work.

• Make sure both lamp housings sit flush with the body and don’t wiggle.
