If you drive a 2017 Jeep Wrangler, you know its design is perfect for both city and off-road adventures. But sometimes, the weather is not on your side. Fog lights help you see better in fog, rain, or snow. Many Wrangler owners are unsure how to turn on these lights or what to do if they do not work. Understanding your fog lights is not just about style — it’s about safety. Let’s look at how to turn on your Wrangler’s fog lights, what to do if you have trouble, and a few extra tips that most people miss.
Where Are The Fog Light Controls?
Every 2017 Jeep Wrangler has a multifunction lever on the left side of the steering wheel. This lever controls your headlights, turn signals, and fog lights. The fog light button is easy to miss if you are not looking for it. On most models, you will find a small button on the end or a ring you can twist near the base of the lever.
Not all Wranglers come with fog lights from the factory, especially base trims. If you do not see the fog light symbol (a lamp with three horizontal lines and a wavy line) anywhere on your controls, your Jeep may not have them installed.
Step-by-step: Turning On Your Fog Lights
Follow these simple steps to use the fog lights on your 2017 Wrangler:
- Start your Jeep. The key must be in the “ON” or “RUN” position.
- Switch on the headlights. Fog lights only work when your headlights are on (either in the parking light or low beam position).
- Locate the fog light control. Look for the fog light symbol on the lever or end knob.
- Activate the fog lights. Push the button or twist the ring. A green indicator with the fog light symbol should light up on your dashboard.
- Check outside. Walk to the front of your Jeep and confirm both fog lights are on.
If the green symbol does not appear, or the lights do not come on, check that your headlights are in the correct position. Fog lights will not work with high beams.
When Should You Use Fog Lights?
Fog lights are designed for low-visibility situations. Use them in:
- Heavy fog
- Rainstorms
- Snowfall
- Dusty roads
They produce a wide, low beam that cuts through mist without blinding other drivers. Do not use fog lights in clear weather, as this can distract other drivers.
Common Problems And Simple Fixes
Sometimes, your fog lights may not turn on. Here are the most frequent issues and what to do:
1. Fog Lights Not Working
- Check the bulb: Fog light bulbs burn out faster than you think, especially with frequent use. A replacement is often cheap and quick.
- Fuse issue: The fog lights have a dedicated fuse. Check the owner’s manual for the exact location in the fuse box and replace it if blown.
- Wiring problem: Off-road use can shake loose wires. Check for visible damage or loose connections.
2. Fog Light Indicator Not Lighting Up
If you do not see the indicator on your dashboard, it usually means the fog lights are not on. Make sure the headlights are in the right position.
3. Only One Fog Light Works
This usually means one bulb is burnt out. Replace both bulbs at the same time to avoid uneven lighting.
Differences Between Trims And Aftermarket Installs
Not every 2017 Wrangler trim has factory fog lights. Higher trims like Sahara and Rubicon usually include them, while base models may not.
If you have installed aftermarket fog lights, the switch might be in a different place. Some kits use a separate button on the dashboard. Always follow the install instructions for your kit.
Wrangler Trim Fog Light Availability
| Trim | Fog Lights (Factory) |
|---|---|
| Sport | Optional |
| Sahara | Standard |
| Rubicon | Standard |
| Willys Wheeler | Optional |
If you want to add fog lights, make sure to buy a kit that fits your Wrangler’s year and model. Some cheap kits may not work with your stock wiring.
Fog Lights Vs. Headlights: Key Differences
Many drivers confuse fog lights with headlights. Here is a quick comparison:
| Feature | Fog Lights | Headlights |
|---|---|---|
| Beam Pattern | Wide and flat | Narrow, long-range |
| Mounting Position | Low, near bumper | Higher on grille |
| Use Case | Fog, rain, snow | All driving |
Two Insights Most Owners Miss
- Fog lights reduce glare only in the right conditions. Using them when it’s clear can actually make it harder to see, not easier.
- Aftermarket wiring can bypass factory safety features. If your fog lights stay on with high beams, a previous owner or installer may have rewired the system. This can be illegal in some states.
Practical Tips For Better Use
- Clean your fog light lenses often. Dirt or scratches can scatter light and reduce visibility.
- Replace both bulbs together for even lighting.
- Only use fog lights when needed; overuse can annoy other drivers and even get you a ticket.
