Replacing the interior lights in your 2014 Jeep Grand Cherokee can make your driving experience safer and more comfortable. Dim or burnt-out bulbs reduce visibility and can be distracting, especially at night. The good news is that you don’t need to be a mechanic to swap these bulbs yourself. With a few simple tools and the right steps, you can restore your car’s interior brightness in under an hour.
Understanding Your Interior Lights
Your 2014 Jeep Grand Cherokee uses several types of interior bulbs. These include the map lights, dome light, cargo area light, footwell lights, and glove box light. Each bulb serves a specific purpose, from illuminating the dash to brightening the rear cargo space. Most original bulbs are halogen, but many owners upgrade to LEDs for longer life and improved brightness.
Tools And Materials You’ll Need
Gathering your tools before you start saves time and prevents frustration. Here’s what you’ll need:
- Flathead screwdriver or trim removal tool
- Phillips screwdriver (for some areas)
- Replacement bulbs (check your owner’s manual for exact sizes)
- Clean gloves (to avoid oil on bulbs)
- Small flashlight (optional)
Using gloves is a small tip that many beginners miss. The oils from your fingers can shorten bulb life or cause hot spots, especially with halogen bulbs.
Replacing Each Interior Light
Let’s go through each interior light location and how to replace the bulb safely.
1. Map Lights (front Overhead Console)
- Gently pry off the clear plastic lens using a trim tool or flathead screwdriver.
- Remove the old bulb by pulling it straight out.
- Insert the new bulb (usually a 194 or 168 size).
- Snap the lens back in place.
Many owners forget to test the bulb before reattaching the lens. It’s easier to replace again if you check now.
2. Dome Light (center Ceiling)
- Insert your tool at the edge of the dome light cover.
- Pry down carefully until the cover pops off.
- Remove the old bulb (typically a festoon style, 31mm).
- Install the new bulb, making sure the metal contacts touch.
- Replace the cover.
If the light does not turn on, rotate the bulb 180 degrees. LED bulbs are polarity-sensitive.
3. Rear Passenger Reading Lights
- Locate the small light near each rear seat.
- Gently pry off the lens.
- Pull out the old bulb (194 or 168).
- Insert the new bulb.
- Snap the lens back on.
4. Footwell Lights
- Look under the dashboard for the small rectangular light assembly.
- Use your trim tool to pop the assembly out.
- Remove the bulb by pulling it straight out.
- Insert the new bulb (often a 194).
- Push the assembly back into place.
This area can be tight. A small flashlight helps you see clearly.
5. Glove Box Light
- Open the glove box fully.
- Find the small lens on the upper side.
- Pry out the lens and pull the bulb (usually a 194) straight out.
- Insert the new bulb.

6. Cargo Area Light
- Open the rear hatch.
- Locate the light assembly on the side panel.
- Insert your tool at the edge and pry out the assembly.
- Remove the old bulb (festoon or 194, check your manual).
- Insert the new bulb.
- Reinstall the assembly.
7. Vanity Mirror Lights
- Flip down the sun visor.
- Pry off the small plastic lens.
- Carefully remove the bulb (usually a small tube shape).
- Insert the new bulb.
- Replace the lens.
Vanity bulbs can be delicate. Handle gently to avoid breaking the glass.
8. Door Courtesy Lights
- Open the door and locate the light at the bottom edge.
- Use a trim tool to pop out the assembly.
- Remove and replace the bulb (194 size).
- Snap the assembly back.
9. Trunk Release Switch Light

Comparing Bulb Types
Here’s a simple comparison between halogen and LED bulbs for your Jeep.
| Feature | Halogen Bulb | LED Bulb |
|---|---|---|
| Brightness | Moderate | High |
| Lifespan | ~1,000 hours | ~25,000 hours |
| Heat Output | High | Low |
| Cost | Low | Higher |
Upgrading to LEDs is common for better visibility and energy savings.
Common Mistakes To Avoid
- Forcing the lens: Always pry gently to avoid cracking plastic.
- Touching bulbs: Use gloves to prevent oils from shortening bulb life.
- Ignoring bulb polarity: If an LED doesn’t work, flip it 180 degrees.
- Using the wrong size: Double-check your manual or use an online bulb guide.
Many DIYers skip the test-before-reassembly step, leading to repeat work.
Estimated Time And Cost
Replacing all interior lights typically takes about 30-45 minutes. Here’s a quick cost estimate.
| Bulb Type | Average Price (Each) | Total Needed | Total Cost |
|---|---|---|---|
| Map/Reading | $2 (halogen) | 4 | $8 |
| Dome/Cargo | $3 (LED) | 2 | $6 |
| Others | $2.50 | 5 | $12.50 |
Expect to pay about $25–$30 for a full LED upgrade, or about $15 if using halogen bulbs.
Final Checks And Safety Tips
- Test all new bulbs before replacing covers.
- Keep your old bulbs as backups.
- Dispose of burnt-out bulbs properly.
If you notice flickering or the new bulb does not work, check the fuse box. A blown fuse can mimic a bad bulb.
