Replacing the third brake light on a 1995 Jeep Cherokee is a practical task that improves safety and keeps your vehicle compliant with traffic laws. Many drivers overlook this small but important fixture, but a working third brake light helps other drivers see you better, especially during sudden stops or bad weather.
Whether your light is dim, broken, or simply not working, this guide will help you swap it out with confidence. Even if you’re new to car repairs, you’ll find clear steps, tips, and answers to common questions here.
Why The Third Brake Light Matters
The third brake light, also called the center high mount stop lamp (CHMSL), sits high on the rear of your Jeep Cherokee. This position makes it easy for drivers behind you to spot your braking, reducing the risk of rear-end collisions. According to the National Highway Traffic Safety Administration, vehicles with a working third brake light are about 5% less likely to be involved in rear-end crashes. For older cars like the 1995 Cherokee, keeping this light functional is both a safety measure and a legal requirement in most states.
Signs You Need To Replace The Third Brake Light
Knowing when to replace your third brake light is key. Here are clear signs:
- Light does not turn on when you press the brake pedal.
- Bulb is visibly burned out or the lens is cracked.
- Warning indicator on your dashboard (if equipped).
- Light is dim or flickers.
- Moisture inside the light housing.
Ignoring these signs can lead to a traffic ticket or unsafe driving conditions.
Tools And Materials Needed
Before you start, gather the right tools. This makes the process smoother and prevents damage:
- Replacement third brake light assembly (check compatibility for 1995 Jeep Cherokee)
- Phillips screwdriver
- Flathead screwdriver
- Socket wrench set
- Electrical contact cleaner
- Clean cloth
- Gloves
- Safety glasses
You might also want a flashlight for better visibility.
Choosing The Right Replacement Light
Not all third brake lights are the same. Here’s how to pick the correct one:
- Check your Cherokee’s trim level (Sport, Country, SE, etc.)
- Match the part number from your old light.
- Look for OEM (Original Equipment Manufacturer) parts for best fit.
- Avoid cheap, unbranded lights—they may not seal properly or may burn out quickly.

Step-by-step Replacement Guide
Follow these steps to replace the third brake light on your 1995 Jeep Cherokee.
1. Prepare Your Workspace
Park your Jeep on a flat surface. Turn off the engine and remove the keys. Put on your safety glasses and gloves.
2. Locate The Third Brake Light
The third brake light is usually mounted at the top center of the rear window or tailgate. On the 1995 Cherokee, it is above the rear hatch.
3. Remove The Old Light
- Use the Phillips screwdriver to unscrew the fasteners holding the light assembly.
- Carefully pry off the light housing with a flathead screwdriver if needed.
- Disconnect the wiring harness by pressing the release tab.
4. Clean The Mounting Area
Wipe the area with a clean cloth and use electrical contact cleaner on the connectors. This prevents corrosion and ensures a solid connection.
5. Install The New Light
- Connect the wiring harness to the new light.
- Align the light assembly and insert it into the mounting area.
- Secure the assembly with screws. Do not overtighten, as this can crack the housing.
6. Test The Light
Press the brake pedal and check if the new third brake light turns on. Ask a friend to help or use a reflective surface to see the light.
7. Reassemble And Finish
If everything works, put away your tools. Dispose of the old light properly.
Common Mistakes And How To Avoid Them
Many beginners make errors that can cause problems later. Here are frequent mistakes:
- Forgetting to disconnect the battery: While not always needed, disconnecting the battery prevents electrical shorts.
- Using the wrong replacement part: Double-check part numbers and compatibility.
- Damaging the wiring harness: Pull gently on connectors; never yank.
- Skipping the cleaning step: Dirt or corrosion can cause the new light to fail early.
A non-obvious tip: If your new light doesn’t work, check the fuse for the brake lights. Sometimes the issue is not the lamp, but the fuse.
Comparison Of Oem Vs Aftermarket Third Brake Lights
Here’s a quick comparison to help you choose between OEM and aftermarket parts:
| Feature | OEM | Aftermarket |
|---|---|---|
| Fit & Compatibility | Guaranteed fit | Varies |
| Price | Higher | Lower |
| Warranty | Usually included | May or may not be included |
| Durability | Long-lasting | Can vary |
If you want a reliable, long-term solution, OEM is best. For budget repairs, aftermarket can work, but check reviews and ratings.
Estimated Costs For Replacing The Third Brake Light
Let’s break down the typical costs for this repair:
| Item | Estimated Cost (USD) |
|---|---|
| OEM third brake light | $45–$70 |
| Aftermarket light | $20–$40 |
| Basic tools | $25–$50 |
| Professional labor (optional) | $60–$100 |
If you do the job yourself, you only pay for the light and tools. A shop will charge extra for labor.
Practical Tips For A Smooth Replacement
- Buy your replacement light from a trusted source.
- Watch out for cheap knock-offs—they often don’t last.
- Use a magnetic tray for screws so you don’t lose them.
- If your wiring looks corroded, consider replacing it for better performance.
- If you live in a rainy area, make sure the new light has a good seal to prevent leaks.
A detail many beginners miss: Take a photo of the wiring before disconnecting anything. This helps you reconnect properly if you get confused.
Troubleshooting After Installation
If the new third brake light doesn’t work:
- Check the brake light fuse.
- Inspect the wiring harness for loose connections.
- Make sure the bulb is seated properly in the socket.
- Test the light with a multimeter for power.
If none of these steps fix the issue, the problem may be elsewhere in the brake light circuit. In rare cases, the brake light switch under the pedal can fail.
Maintenance Tips To Extend The Life Of Your Third Brake Light
- Clean the lens every few months to keep it bright.
- Inspect for moisture, which can cause corrosion.
- Replace bulbs as soon as they dim.
- Avoid washing with harsh chemicals that can crack the plastic.
If your light repeatedly fails, check for electrical issues or water leaks in the hatch area.
Comparison Of Diy Vs Professional Replacement
Here’s a look at the pros and cons of replacing the third brake light yourself versus hiring a professional:
| Aspect | DIY | Professional |
|---|---|---|
| Cost | Lower | Higher |
| Time | 30–60 minutes | 15–30 minutes |
| Skill needed | Basic tools & knowledge | None |
| Warranty | No labor warranty | Usually included |
| Risk of mistakes | Moderate | Low |
DIY is rewarding and cost-effective. Professional help is faster and comes with a guarantee.
