⚠️ Safety & Precautions

• ⚠️ Work on level ground and set the parking brake.
• ⚠️ Let lights cool before touching the bulb.
• ⚠️ Don’t touch the new bulb glass with bare fingers (oil can shorten bulb life).
• ⚠️ If you remove a wheel, support the Jeep with jack stands—never rely on a jack alone.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear tires.
• Turn the steering wheel fully to the side you’re working on (gives more room in the wheel well).
• Tip: You usually don’t need to remove the wheel.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Create access in the front wheel well

• Turn the steering wheel to open up space near the front of the wheel well.
• Use a flashlight to find the back side of the front fender/flare lamp area.
• If the inner liner blocks access, remove the needed fasteners:
• Use a trim clip removal tool to pop out plastic push clips (a trim clip tool is a fork-shaped pry tool that removes plastic clips without breaking them).
• Use a 7mm socket with a 1/4" drive ratchet and/or a Phillips screwdriver to remove any small screws holding the liner edge.

Step 2: Remove the turn signal bulb socket

• Locate the bulb socket going into the back of the lamp housing.
• Grip the socket and rotate it counterclockwise about 1/4 turn to unlock it.
• Pull the socket straight out of the housing.

Step 3: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new amber 3157NA bulb by pushing it straight into the socket until fully seated.
• Wear nitrile gloves to keep skin oils off the bulb.

Step 4: Reinstall the socket and liner

• Insert the socket back into the lamp housing.
• Turn the socket clockwise about 1/4 turn until it locks.
• Reinstall the inner fender liner fasteners using the 7mm socket, 1/4" drive ratchet, Phillips screwdriver, and press-in clips by hand.

Step 5: Optional wheel removal (only if you need more room)

• Loosen lug nuts slightly using a 19mm socket and torque wrench (or ratchet) before lifting.
• Lift at the approved jacking point with a floor jack (rated 3-ton minimum) and support with jack stands (rated 3-ton minimum).
• Reinstall wheel and tighten lug nuts in a star pattern: Torque to 176 Nm (130 ft-lbs).

✅ After Repair

• Test the left and right turn signals and the hazard lights.
• Make sure the turn signal flashes at a normal speed (a fast flash usually means a bulb isn’t seated or a bulb is out).
• Check that the socket is fully locked—loose sockets can let water into the housing.
