Having working tail lights is not just about safety; it’s also the law.
A broken tail light can get you pulled over and fined. Here’s how you can change the tail light bulb in your 1996 Jeep Grand Cherokee even if you’re not a car expert.
What You’ll Need
Before you start, make sure you have:
- New tail light bulb (model 3157 or equivalent)
- Phillips screwdriver
- Clean gloves (optional but keeps oils off bulb)
- Small flathead screwdriver (if needed)
Step-by-step Guide To Changing The Tail Light Bulb
1. Turn Off Your Jeep
Always turn off your vehicle and remove the key. This avoids electrical shocks and keeps you safe.
2. Locate The Tail Light Assembly
Open the rear hatch. Look at the side of the tail light housing.
You’ll see two or three screws holding the tail light assembly in place.
3. Remove The Tail Light Assembly
Use your Phillips screwdriver to unscrew the mounting screws. Place the screws somewhere safe so you don’t lose them.
Gently wiggle the tail light assembly away from the car. If it feels stuck, gently pry the edge with a flathead screwdriver.
Don’t pull too hard the wires are still connected.
4. Access The Bulb Socket
Look at the back of the assembly. You’ll see a set of wires leading to bulb sockets.
Find the socket for the tail light bulb it’s usually the middle or bottom socket.
Turn the socket counterclockwise about a quarter turn, then pull it out of the assembly.
5. Remove The Old Bulb
Hold the socket and gently pull the bulb straight out. If it’s stuck, wiggle it slightly.
Avoid twisting, as this can break the bulb.
6. Install The New Bulb
Take the new 3157 bulb and, using gloves or a clean cloth, push it firmly into the socket. Make sure it’s seated all the way.
7. Test The Bulb
Before putting everything back, test the new bulb. Have someone press the brake pedal or turn on the lights.
If the bulb lights up, you’re good to go. If not, check that it’s installed correctly.
8. Reassemble The Tail Light
Insert the socket back into the assembly and turn it clockwise to lock it in place. Align the assembly with the holes and press it back onto the car. Replace and tighten the screws.
Close the rear hatch and give the tail light a gentle shake to be sure it’s secure.
Useful Tips For A Smooth Bulb Replacement
- Don’t touch the glass of the new bulb with your fingers. Oil from your skin can shorten bulb life.
- If the bulb still doesn’t work, check the fuse box. A blown fuse can also cause tail lights to stop working.
- Keep spare bulbs in your glove box; they’re cheap and can save you trouble on the road.
Common Mistakes To Avoid
- Forcing the bulb into the socket. If it doesn’t fit, check you have the right model.
- Losing screws. Place them in a cup or tray.
- Not checking the bulb before reassembling everything. Always test the new bulb first.
- Mixing up bulbs. The tail light assembly may contain several bulbs (brake, reverse, signal). Double-check you’re replacing the right one.

What If The Problem Isn’t The Bulb?
Sometimes, replacing the bulb doesn’t fix the issue. In that case:
- Check the fuse: The fuse box is under the dashboard. Look for the one labeled “tail light” and see if it’s blown.
- Check wiring: Broken or corroded wires can also cause problems. If you’re unsure, consult a mechanic.
- Test the socket: Sometimes the socket itself is faulty. If you have a multimeter, check for power.
Why Tail Lights Matter
Tail lights keep you visible to other drivers at night and during bad weather. In 2021, the NHTSA reported that rear-end collisions made up 29% of all car crashes in the US. A working tail light can literally save lives.
