If you drive a 2020 Jeep Wrangler, you know this vehicle is built for adventure. But when fog rolls in, visibility can drop fast, making driving dangerous. That’s when fog lights become essential. Knowing how to turn them on is simple, but there are some details and common mistakes that new owners often miss. In this guide, you’ll learn exactly how to use your Wrangler’s fog lights, plus practical tips, troubleshooting advice, and answers to common questions. By the end, you’ll feel confident using this feature, even in tough weather.
Understanding Fog Lights On The 2020 Jeep Wrangler
Fog lights are designed to cut through mist, rain, and snow by casting a wide, low beam. The 2020 Jeep Wrangler includes fog lights as standard on most trims, like Sport S, Sahara, and Rubicon. These lights are mounted low on the front bumper, helping reduce glare and improve road visibility.
Some stats show that fog lights can improve visibility by up to 30% in dense fog compared to standard headlights. That makes them a valuable safety feature, especially during early morning or late night drives.
Key Features
- Wide beam pattern reduces glare.
- Low placement helps illuminate the road surface.
- Easy access controls from inside the cabin.
How To Turn On Fog Lights: Step-by-step
Turning on your fog lights in a 2020 Jeep Wrangler is straightforward. Here’s how to do it:
1. Start The Vehicle
Turn the ignition on. Fog lights will not operate if the engine is off.
2. Switch On Headlights
Fog lights only activate when your headlights are on. Rotate the headlight switch to the “Auto” or “On” position.
3. Locate Fog Light Control
The fog light button is part of the headlight control dial, found on the left side of the dashboard near the steering wheel.
Push the fog light icon (usually a button with a horizontal line and three downward lines). A green indicator light will show on your dashboard when fog lights are active.
5. Check Exterior Lights
Get out and confirm both fog lights are shining. If not, check for blown bulbs or a fuse issue.
Tips For Safe Use
- Only use fog lights in low visibility. Using them in clear weather can blind other drivers.
- Turn fog lights off when conditions improve.
- Remember, fog lights turn off automatically when you switch to high beams.
Comparing Fog Lights To Other Lighting Options
To understand the difference, here’s a quick comparison between fog lights, headlights, and high beams:
| Lighting Type | Beam Pattern | Best Used For |
|---|---|---|
| Fog Lights | Wide, low | Fog, mist, heavy rain |
| Headlights | Narrow, forward | Normal night driving |
| High Beams | Long, straight | Empty roads, no oncoming traffic |
Fog lights are most effective when regular headlights cause glare and reduce your ability to see the road.
Common Mistakes When Using Fog Lights
Many Jeep owners make mistakes that can reduce safety or cause legal trouble.
1. Using Fog Lights In Clear Weather
This can dazzle other drivers and is illegal in some states.
2. Forgetting To Turn Off Fog Lights
Leaving fog lights on after the fog clears can drain your battery if you idle for long periods.
3. Trying To Use Fog Lights With High Beams
Most vehicles, including the Wrangler, disable fog lights when high beams are on.
4. Ignoring Indicator Lights
If the dashboard shows a fog light warning, check for bulb or fuse problems immediately.
Troubleshooting Fog Light Issues
If your fog lights don’t turn on, here are some quick steps:
1. Check The Headlight Setting:
Fog lights only work with low beams.
2. Look For Blown Bulbs:
Replace faulty bulbs with the correct size (H11 for most 2020 Wranglers).
3. Inspect Fuses:
The fuse box is under the hood. Look for the fog light fuse and replace if necessary.
4. Test The Switch:
If the button feels loose or doesn’t click, it may need repair.
Fog Light Bulb Replacement Cost
Here’s a comparison of average costs:
| Replacement Type | Average Cost (USD) |
|---|---|
| DIY (bulb only) | $20-$40 |
| Professional service | $60-$120 |
DIY is cheaper, but professional service ensures correct installation.
Real-world Example
Imagine you’re driving in rural Colorado early morning. Thick fog rolls in, and visibility drops to 100 feet.
Turning on your Wrangler’s fog lights instantly improves your ability to see lane markings and road hazards. By keeping your fog lights on and high beams off, you avoid glare and drive safely until conditions improve.
Practical Insights For Beginners
- Fog lights are not substitutes for headlights.
- If your Wrangler has aftermarket bumpers, check if fog lights are still connected—they can be unplugged during upgrades.
- Fog light bulbs last about 2-3 years with regular use. Replace them before they fail, not after.
One thing many beginners miss: fog light performance drops if your bumper is dirty. Clean both lights regularly for maximum brightness.
Fog Light Performance Data
In a recent test, drivers using fog lights in dense mist reduced reaction time by 15% compared to headlights alone. That could be the difference between avoiding an obstacle and a collision.
| Condition | Average Visibility Increase |
|---|---|
| Heavy Fog | +30% |
| Light Mist | +20% |
| Rain | +15% |
