Adding spot lights to your 2016 Jeep Wrangler is one of the most practical upgrades you can make for better visibility and style. Whether you love night off-roading or simply want a bolder look, spot lights help you see farther and avoid obstacles. Installing them yourself might sound complex, but with the right steps, tools, and tips, you can do it safely at home. Let’s walk through the process so you get bright, reliable spot lights on your Wrangler—without headaches or mistakes.
Why Install Spot Lights On A 2016 Jeep Wrangler?
Spot lights are more than just a cool accessory. They provide focused beams of light, which help you see further ahead compared to factory headlights. This is especially useful for night driving, off-roading, or traveling in poorly lit areas. Many Jeep owners choose spot lights for:
- Improved safety: Spot lights make it easier to spot hazards, animals, or obstacles.
- Style: A rugged look that stands out.
- Off-road advantage: Illuminates trails, rocks, and deep ruts at night.
A 2016 Wrangler is designed for upgrades, making installation straightforward if you follow the right steps.
What You Need Before You Start
Gathering the correct tools and spot light kit is essential. Here’s what you need:
- Spot light kit (with lights, wiring harness, relay, and switch)
- Mounting brackets (specific to Jeep Wrangler)
- Socket set and wrenches
- Screwdrivers (Phillips and flathead)
- Wire stripper/crimper
- Electrical tape
- Zip ties
- Drill and bits (if mounting holes are not pre-drilled)
- Multimeter (for checking connections)
- Protective gloves and safety glasses
Choosing a good spot light kit is important. Look for waterproof, shock-resistant lights with at least 2,000 lumens per light for strong illumination.
Choosing The Right Spot Lights
Not all spot lights are equal. Here’s a quick comparison of key factors:
| Feature | Basic Spot Light | Premium Spot Light |
|---|---|---|
| Lumens | 1,500-2,000 | 3,000+ |
| Waterproof Rating | IP65 | IP68/IP69K |
| Housing Material | Plastic | Aluminum |
| Lifespan | 10,000 hrs | 30,000+ hrs |
For most Jeep drivers, a premium spot light is worth the extra cost, offering longer life and better weather protection.
Planning The Installation
Before you start, decide where to mount your spot lights. Common locations include:
- A-pillar (beside windshield)
- Front bumper
- Roof rack
Each location has pros and cons. A-pillar mounts are popular because they’re easy to reach and wire, while bumper and roof lights give broader illumination. Always check your local laws some states require lights to be covered on public roads.
Step-by-step Guide To Installing Spot Lights
1. Prepare Your Jeep
- Park on a flat surface and set the emergency brake.
- Disconnect the negative battery cable to avoid electrical shocks.
2. Install Mounting Brackets
Most spot lights require mounting brackets. For a 2016 Wrangler:
- Remove the screws from the A-pillar or bumper (depending on your chosen spot).
- Position the bracket and secure it with the original screws or bolts. If needed, drill holes using the correct drill bit size.
- Tighten bolts firmly but do not overtighten—you don’t want to crack plastic or strip threads.
3. Attach The Spot Lights
- Bolt the spot light to the bracket.
- Adjust the angle so it points straight ahead or slightly down for best visibility.
- Hand-tighten first, then use a wrench to finish.
4. Run The Wiring Harness
A good wiring harness makes installation much easier. Here’s how to route it:
- Connect the harness plug to each spot light.
- Route the wires along the engine bay or under the hood, away from hot or moving parts.
- Secure wires with zip ties.
- Pass the switch wire through the firewall (there’s usually a rubber grommet you can use).
5. Mount The Switch
- Choose a spot inside the cabin (often near the dashboard).
- Drill a small hole if needed.
- Push the switch into place and connect the wires as shown in the instructions.
6. Connect Power And Ground
- Attach the relay’s power wire to the positive battery terminal.
- Connect the ground wire to a clean, bare metal surface on the Jeep’s chassis.
- Double-check all connections for tightness.
7. Test The System
- Reconnect the battery.
- Turn on the switch and check if the spot lights work.
- Adjust the light angle as needed.
- If a light does not turn on, check all connections with a multimeter.
Important Safety Tips
- Always wear safety glasses when drilling.
- Disconnect the battery before working with wiring.
- Route wires away from moving engine parts and areas that get hot.
- Use relay and fuse to prevent electrical overloads.
Common Mistakes And How To Avoid Them
Many beginners make these errors:
- Skipping the relay: Running spot lights without a relay can overheat your switch or wiring.
- Poor ground connection: A weak ground causes flickering or dim lights.
- Wiring too close to hot parts: Heat can melt insulation and cause shorts.
- Not sealing connections: Use electrical tape and waterproof connectors to keep out moisture.
Wiring Diagram Example
Understanding the wiring is easier with a visual. Here’s a simple example:
- Battery positive → Relay → Spot lights
- Switch → Relay control wire
- Spot lights ground → Chassis
Most wiring harnesses include a fuse make sure it’s rated for your light’s amp draw (usually 15-30A).
How To Aim Your Spot Lights
Proper aiming is key for best performance:
- Park 25 feet from a wall.
- Turn on the spot lights.
- Adjust so the brightest spot is just below headlight level.
- Tighten all bolts after aiming.
Misaligned lights can blind other drivers or miss the road ahead.
Maintenance Tips For Long Life
Spot lights last longer with simple care:
- Clean the lenses every few weeks.
- Check mounts and wiring after off-road trips.
- Replace any cracked or water-damaged parts quickly.
If you notice flickering, check for loose connections or moisture in the housing.
Comparing Mounting Locations
Different mounting spots offer unique benefits:
| Location | Visibility | Ease of Install | Style Impact |
|---|---|---|---|
| A-pillar | Good forward | Easy | Subtle, OEM-like |
| Bumper | Wide, low | Medium | Rugged, aggressive |
| Roof | Wide, far | Hard | Very bold |
For most 2016 Wrangler owners, A-pillar mounting offers the best mix of function and appearance.
Real-world Example
Maria, a Jeep owner in Colorado, installed 3,200-lumen spot lights on her 2016 Wrangler. She chose A-pillar mounts and a relay wiring harness. After installation, she reported much better visibility on mountain trails at night. Her main advice: “Take your time with the wiring. A clean install means fewer problems later.”
Cost Breakdown
Expect to spend:
- Spot light kit: $50–$200
- Mounting brackets: $20–$50
- Wiring harness: Usually included, $10–$30 if separate
- Tools/supplies: $0 (if you already own) to $50
Total: $70–$300 depending on the quality and features you choose.
When To Get Professional Help
If you are not comfortable with car wiring, it’s wise to ask a professional installer. Modern Jeeps have complex electronics, and mistakes can cause electrical problems. Shops usually charge $100 $200 for spot light installation.
