Replacing the rear brake light on your 2016 Jeep is a simple task that can make a big difference for your safety and visibility on the road.
Many drivers don’t realize how important a working brake light is until they get pulled over or, worse, someone rear-ends them because their brake lights were out.
The good news is, you don’t need to be a mechanic to do this job yourself.
With a few basic tools, a bit of patience, and this step-by-step guide, you’ll have your new brake light installed in no time and avoid unnecessary tickets or accidents.
Why Rear Brake Lights Matter
Your rear brake lights are a critical safety feature. When you press the brake pedal, these lights signal to drivers behind you that you’re slowing down or stopping. A burned-out brake light puts you and others at risk, especially at night or in bad weather. In the US, driving with a faulty brake light can also get you a ticket. So, it’s smart to check your brake lights regularly and replace them as soon as they stop working.
Tools And Materials You’ll Need
Before you get started, gather the following items:
- Replacement bulb (check your owner’s manual for the correct type, usually 3157 or 7443 for a 2016 Jeep)
- Screwdriver (usually Phillips-head)
- Socket wrench (optional, depending on your Jeep model)
- Clean cloth or gloves
- Small flathead screwdriver (for prying, if needed)
Having everything ready before you start will help the process go smoothly.
Preparing Your Jeep
First, park your Jeep on a flat surface and turn off the engine. Make sure the vehicle is in park and the parking brake is engaged. If possible, work during the day or in a well-lit area. If you need to check which brake light is out, ask a friend to press the brake pedal while you look at the rear lights.
Step-by-step Guide To Replacing The Rear Brake Light
1. Open The Trunk Or Tailgate
Open the tailgate (for Jeep Wrangler, Cherokee, or similar models) or trunk to access the rear light housing. This gives you room to work and lets you reach the back of the brake light assembly.
2. Locate The Rear Light Assembly
The rear light assembly is the section that holds the brake light, turn signal, and reverse light. It’s usually secured with a few screws or bolts, which you’ll need to remove.
3. Remove The Light Assembly
Most 2016 Jeeps use two or three screws to hold the light assembly in place. Use your screwdriver or socket wrench to carefully unscrew them.
Keep the screws in a safe spot you’ll need them to put everything back together.
Pro tip: If the light assembly feels stuck, gently pry it out with a small flathead screwdriver. Be careful not to scratch the paint.
4. Disconnect The Wiring Harness
Once the assembly is loose, gently pull it away from the vehicle. You’ll see a wiring harness connected to the back. Press the tab on the connector and pull it out to disconnect the wires. Now you can take the assembly to a workbench or flat surface.
5. Find And Remove The Brake Light Bulb
On the back of the assembly, you’ll see several bulb sockets. The brake light bulb is usually the middle or largest one.
Twist the bulb socket counterclockwise and pull it out. Carefully remove the old bulb by pulling it straight out.
Non-obvious insight: Some bulbs can be tricky to remove if they’re stuck. Wiggle the bulb gently instead of pulling hard, to avoid breaking it.
6. Install The New Bulb
Take your new brake light bulb and, using a clean cloth or gloves (to avoid getting oils from your fingers on the bulb), push it firmly into the socket. Make sure it’s seated fully.
7. Test The New Bulb
Before putting everything back together, reconnect the wiring harness and have someone press the brake pedal. Check to see if the new bulb lights up.
If it doesn’t, double-check that the bulb is installed correctly and the wiring harness is connected.
8. Reassemble The Light Assembly
Once you confirm the new bulb works, reinsert the bulb socket into the assembly and twist it clockwise to lock it in place. Reconnect the wiring harness and carefully fit the assembly back into the vehicle. Replace and tighten the screws.
9. Final Check
With everything back in place, test the brake lights again. If both sides work, you’re done!
Choosing The Right Replacement Bulb
The correct bulb type is crucial. Using the wrong bulb can cause electrical problems or may not fit at all. For most 2016 Jeep models, the 3157 or 7443 bulbs are common choices, but always double-check your owner’s manual.
Here’s a quick comparison of common bulb types:
| Bulb Type | Lifespan (hours) | Brightness (lumens) | Fits 2016 Jeep? |
|---|---|---|---|
| 3157 | 1,200 | 402 | Yes |
| 7443 | 1,000 | 410 | Yes |
| 1157 | 500 | 400 | No |
LED bulbs last much longer than traditional incandescent bulbs. If you want a longer-lasting solution, consider upgrading to LED brake lights. They use less power and are brighter, but they may cost more upfront.
Common Mistakes To Avoid
- Touching the bulb glass: Oils from your fingers can make bulbs burn out faster. Always use a cloth or gloves.
- Forgetting to test before reassembly: If the new bulb doesn’t work, you’ll have to take everything apart again.
- Using the wrong bulb type: Double-check the part number before buying.
- Over-tightening screws: This can crack the plastic housing.
How Often Should You Check Your Brake Lights?
Experts recommend checking your brake lights every few months. It’s especially important before long trips or during rainy seasons.
If you drive mostly in the city, where you use brakes more often, your bulbs may burn out faster.
Extra Tips For A Smooth Replacement
- If your Jeep has a tail light assembly cover, you might need to remove it first.
- Some models have a small access panel inside the trunk for easier bulb changes.
- If your new bulb still doesn’t work, check the fuse or wiring for damage.
- Take a quick photo of the assembly before you start. It helps if you forget how things go back together.
Cost Of Replacing A Rear Brake Light
The cost for a new brake light bulb is usually between $5 and $15. If you choose LED bulbs, expect to pay $20–$40 for a pair. Doing the job yourself saves on labor, which can cost $30–$50 at a repair shop.
Here’s a look at the costs:
| Item | DIY Cost | Shop Cost |
|---|---|---|
| Standard Bulb | $5–$15 | $35–$65 |
| LED Bulb | $20–$40 | $50–$80 |
Environmental Impact Of Brake Light Bulbs
Traditional bulbs need to be disposed of properly. LED bulbs, while more expensive, last longer and are more energy efficient.
When you upgrade to LEDs, you reduce waste and save energy in the long run. Always recycle old bulbs when possible many auto parts stores accept them.
Real-world Example
One Jeep owner replaced their rear brake light in less than 15 minutes with just a screwdriver and a new bulb. They saved about $40 compared to going to a shop. They also avoided a potential ticket for a broken brake light. Simple tasks like this can add up to big savings over time.
When To Seek Professional Help
If you notice any of these issues, it might be time to visit a mechanic:
- Brake light still doesn’t work after bulb replacement
- Signs of water or moisture inside the light assembly
- Broken wiring or damaged socket
Sometimes, the issue is with the electrical system or the fuse, not just the bulb.
Safety Reminders
- Always make sure your Jeep is off and parked securely before you start.
- Avoid working on a hot bulb; let it cool first.
- Keep tools and small parts out of reach of children.

Can I Use Led Bulbs Instead Of Standard Bulbs?
Yes, LED bulbs are compatible with most 2016 Jeep models. They last longer and are brighter, but make sure they fit your specific assembly. Some models may need a resistor to prevent hyper-flashing.
