How to Replace the Taillight Bulb in a 2007 Jeep Cherokee

by Ziggy Thomas

Replacing taillights is an easy process that can be done by the novice mechanic quickly and easily. Replacing light bulbs in your vehicle takes less than a half hour. The type of light bulb you will need for your 2007 Jeep Grand Cherokee is part number 4157NA/K. Replacement bulbs can be purchased from most hardware stores or auto parts retailers.

Step 1

Raise the lift gate of your Jeep Cherokee to access the taillight's cover.

Step 2

Remove the two connecting screws with a Torx head screwdriver.

Step 3

Squeeze the socket assembly tabs to remove the socket from the vehicle.

Step 4

Pull the bulb away from the taillight to remove it from the socket.

Step 5

Replace the old bulb with the new one by inserting it into the socket. Avoid touching the bulb with your fingers as contact with skin oils can shorten its lifespan. If you do touch the bulb, it can be cleaned with rubbing alcohol.

Step 6

Reinstall the socket into the taillight by squeezing the socket assembly tabs and inserting it into place. When the socket is secure in the taillight, it should not shake or move. If the socket seems loose, push it further into the taillight until you hear it click into place.

Reattach the light assembly with the Torx head screwdriver.

Tip

  • There are three bulbs in the taillight. The top light is the brake light bulb, the middle light is the signal bulb, and the bottom light is the back-up light bulb.
