Changing the license plate light on your 2018 Jeep Renegade is a small but important maintenance task. A working license plate light is not just about avoiding tickets—it's key for safety and visibility at night.
Many drivers overlook this simple detail until it's time for a state inspection or they get pulled over. The good news?
Swapping the bulb is straightforward, and you don't need advanced tools or car knowledge.
This guide takes you step-by-step through the process. You'll learn which bulb to buy, which tools you'll need, and how to avoid common mistakes.
Whether you're a first-time DIYer or just want to save money on dealership labor, you'll find clear instructions here.
Let’s get started and make sure your Renegade stays both legal and safe on the road.
Why Your License Plate Light Matters
The license plate light helps police, other drivers, and cameras see your plate clearly at night. In most states, driving with a burned-out plate light is a traffic violation. More importantly, a working light can help in emergencies, as your plate remains visible to responders. For a 2018 Jeep Renegade, the light is positioned right above the rear plate.
What You Need Before You Start
Gathering the correct items makes the process much smoother. Here’s what you’ll need:
- Replacement bulb: For the 2018 Jeep Renegade, the standard bulb type is W5W (T10). Check your owner’s manual or remove the old bulb to confirm.
- Small flathead screwdriver or plastic trim tool
- Gloves (optional, to keep oils off the bulb)
- Clean rag
Not all replacement bulbs are the same. LED bulbs are brighter and last longer but may cost more. Traditional halogen bulbs are cheaper but burn out faster.
How To Change The License Plate Light
Changing your Renegade’s license plate bulb takes about 10 minutes. Follow these steps for a smooth process.
1. Turn Off The Vehicle
Always switch off your Jeep and remove the key. This ensures safety and prevents any electrical shorts.
2. Locate The License Plate Light Housing
Look above the rear license plate. You’ll see a small, clear plastic cover—the light housing. The 2018 Renegade typically has two lights: one above each side of the plate.
3. Remove The Light Housing
Use a small flathead screwdriver or plastic trim tool. Gently insert it into the notch on the side of the housing.
Carefully pry it out, being cautious not to crack the plastic.
Pro tip: Wrap the screwdriver tip in a rag to prevent scratches.
4. Take Out The Old Bulb
Once the housing is free, pull it out just enough to access the bulb. The bulb usually pulls straight out no twisting required.
5. Install The New Bulb
Hold the new bulb by its base (not the glass). Insert it into the socket. If you’re using an LED bulb, test it before snapping the housing back in—LEDs have polarity and may only work one way.
6. Reattach The Light Housing
Push the housing back into place until it clicks. Make sure it sits flush so water can’t get in.
7. Test The Light
Start your Jeep and turn on your headlights. Walk around to the back and check that the license plate light is working.
If it’s not, check the bulb for correct orientation or try another bulb.
Common Mistakes And How To Avoid Them
Even simple jobs have pitfalls. Here are common issues and tips to avoid them:
- Wrong bulb type: Always double-check the number on the old bulb or your manual.
- Touching the bulb glass: Oils from your fingers can shorten bulb life.
- Forcing the housing: Applying too much force can crack the plastic.
- LEDs not lighting up: Flip the LED bulb if it doesn’t work at first—LEDs are directional.
Comparing Bulb Types
Here’s a quick look at the difference between standard halogen and LED bulbs for your Renegade’s license plate:
| Type | Brightness | Lifespan | Cost |
|---|---|---|---|
| Halogen | Standard | 1-2 years | Low |
| LED | Very Bright | 5+ years | Medium to High |
LEDs are more efficient and last longer but can be more expensive upfront.
Signs Your License Plate Light Needs Replacement
Sometimes, you won’t notice your license plate light is out until someone tells you. Here are signs to look for:
- The license plate area is dark at night.
- You get a warning light on your dashboard.
- You are stopped by police for a light violation.
Regularly checking your lights when refueling or washing your Renegade helps catch issues early.
Step-by-step With Images (what You’ll See)
The process is straightforward, but here’s what you’ll see at each step:
- Plastic cover above the plate—slightly cloudy or clear.
- Small slot at the side for your screwdriver.
- The old bulb will look small, glass, and about an inch long.
- The new bulb slides in—no twisting.
- The plastic housing clicks back in—no screws.
Tips For A Longer-lasting Fix
- Choose quality bulbs: Not all W5W bulbs are the same; stick with trusted brands.
- Consider LEDs: You won’t need to change them as often.
- Check both sides: If one bulb is out, the other may be close behind.
- Keep a spare bulb in your glove compartment.
What If The Light Still Doesn’t Work?
If you’ve replaced the bulb and the light still won’t turn on, try these troubleshooting steps:
- Check the fuse: The license plate light shares a fuse with other rear lights.
- Inspect the wiring: Look for corrosion or loose wires.
- Check the socket: Sometimes water gets in and rusts the contacts.
For persistent issues, a certified mechanic can run a full electrical check.
Cost Comparison: Diy Vs. Dealership
Doing it yourself saves money. Here’s a quick comparison:
| Service Option | Parts | Labor | Total |
|---|---|---|---|
| DIY (Halogen) | $2–$5 | $0 | $2–$5 |
| DIY (LED) | $8–$20 | $0 | $8–$20 |
| Dealership | $5–$20 | $25–$50 | $30–$70 |
As you can see, changing the bulb yourself costs a fraction of a dealership visit.
Safety And Legal Notes
Driving without a license plate light can lead to fines. Police often use this as a reason to pull drivers over.
More importantly, a well-lit plate ensures your vehicle is easily identified if needed.
Environmental Considerations
LED bulbs use less power and last much longer. That means less waste and fewer trips to the parts store. If you want to minimize your environmental footprint, switching to LED is a smart choice.
When To Seek Professional Help
If you notice melted plastic, damaged wiring, or repeated bulb failures, don’t risk it. Electrical issues can cause other lights to fail or even short out your Jeep’s system.
A certified technician can quickly diagnose deeper problems.
