Turning on the daytime running lights (DRL) in a Jeep Wrangler seems simple, but owners often find it confusing. DRLs are a safety feature that helps your vehicle stay visible during the day. Some Jeep Wranglers have DRLs by default, while others need a manual setup. If you are unsure how to activate them or why they matter, this guide will help you get it right.
Understanding Daytime Running Lights In Jeep Wrangler
Daytime running lights are low-power lights on the front of your car. They turn on when the engine is running and headlights are off. DRLs are not as bright as regular headlights but make your Jeep easier to see, especially in bad weather or low-light areas.
Many countries require DRLs by law. In the US, more cars now come with DRLs from the factory. According to the National Highway Traffic Safety Administration, DRLs can reduce daytime accidents by up to 11%. In 2021, Jeep added DRLs as standard in most Wrangler trims, but older models may not have them enabled.
Checking Your Jeep Wrangler’s Drl Setup
Before you try to turn on DRLs, you need to know if your Wrangler supports them and how they work in your model year. The steps can change based on the year and trim.
| Model Year | DRL Feature | Activation Method |
|---|---|---|
| 2018-2024 (JL/JLU) | Standard on most trims | Via Uconnect menu or automatic |
| 2015-2017 (JK/JKU) | Optional or region-specific | Dealership programming |
| 2007-2014 (JK) | Rare, mostly Canadian models | Wiring change or module |
If you are not sure about your trim, check your owner’s manual or look for a DRL symbol on the dash.
Steps To Turn On Daytime Running Lights
The way you turn on daytime running lights depends on your Jeep’s model year and system.
For 2018 And Newer Jeep Wrangler (jl/jlu)
Most new Wranglers let you control DRLs through the Uconnect system.
- Start the engine and keep the Jeep in ‘Park.’
- Tap the ‘Settings’ icon on your Uconnect screen.
- Scroll to ‘Lights’ or ‘Exterior Lights.’
- Find Daytime Running Lights in the menu.
- Turn the toggle switch to ‘On.’
DRLs will now activate every time you start the engine. If you do not see this option, your trim may not support manual control.
For 2015-2017 Wrangler Jk/jku
Some JK models have DRLs as a software setting, but it is often disabled in the US.
- Visit your Jeep dealership.
- Ask them to enable DRL through the vehicle’s computer (TIPM or BCM).
- This process may have a small fee.
After activation, DRLs will operate automatically.
For 2007-2014 Wrangler Jk
These Wranglers usually lack DRLs unless made for Canada. If you want DRLs:
- Install a DRL module (aftermarket part)
- Or, have a technician re-wire the fog lights or turn signals to act as DRLs
Always use a certified mechanic for wiring changes to avoid electrical problems.
Customizing Drl Behavior
Some Jeep Wranglers allow you to change how DRLs work.
| Setting | Description | How to Change |
|---|---|---|
| On with ignition | DRLs light up when engine is on | Uconnect or dealer |
| Off with headlights | DRLs turn off when headlights are on | Automatic |
| Brightness | Adjust DRL intensity (rare) | Some trims via Uconnect |
Not all settings are available in every model. If you do not see options, your Jeep may not support them.
Common Issues And Solutions
Some owners turn on DRLs and still see problems. Here are typical issues and what to do:
- DRLs not visible: Make sure bulbs are not burned out.
- No DRL option in menu: Your trim may not support it, or it needs dealer activation.
- DRLs stay on with headlights: This is normal in some trims. Check your manual.
- Dashboard error after wiring DRLs: Faulty wiring or wrong module. Have a pro check it.
Non-obvious tip: Some aftermarket LED headlight upgrades can cause DRL errors or flicker. Use Jeep-certified parts to avoid these issues.
Safety And Legal Considerations
DRLs are legal in all US states, but local laws can affect how you use them. In some states, you must use headlights in bad weather, even if DRLs are on. DRLs do not replace regular headlights at night.
Non-obvious insight: Disabling DRLs may void your warranty or cause your Jeep to fail inspection in some regions. Always check your local laws before making changes.
Benefits Of Using Daytime Running Lights
Turning on DRLs is not just about following the rules. They offer clear benefits:
- Better visibility: Other drivers see you sooner.
- Lower crash rates: Studies show fewer daytime accidents.
- Insurance savings: Some companies offer small discounts for cars with DRLs.
In a 2020 study, cars with DRLs had a 5.9% lower daytime crash rate compared to cars without them. This small change can make a big safety difference.
