I’ll be the first to admit it, there’s something undeniably cool about underglow lights. I remember seeing them on tuner cars growing up and thinking, one day I’m going to install those. Fast forward to today, and underglow kits have come a long way: they’re brighter, smarter, and easier to install than ever. But here’s the catch, just because you can install underglow doesn’t mean it’s legal to use everywhere you drive.
If you’re thinking about adding LED underglow to your daily driver, here’s what I’ve learned about keeping it safe, street legal, and slick.
What Is LED Underglow?
Underglow lighting refers to LED strips mounted underneath your vehicle that illuminate the ground beneath it. These kits often come with remote controls or smartphone apps that let you customize colors, patterns, and brightness.
Is Underglow Legal for Daily Driving?
This is the number one question people ask—and it’s a smart one. The short answer? Yes, underglow can be legal, but it depends entirely on how and where you drive.
General Rules Across Most U.S. States:
- No red or blue lights visible from the front (reserved for emergency vehicles)
- No flashing or strobing patterns (can be mistaken for police)
- Underglow must not be distracting to other drivers
- Avoid colors that resemble brake or turn signals
If you’re using a single color like white or amber, keeping it dim and non-flashing, and sticking to roads where it’s not heavily regulated, you’re usually fine. But always double-check your local DMV’s vehicle lighting laws. Some states (like California) are stricter than others.
My Daily Driver Setup (and Why It Works)
I drive a late-model Civic and commute daily, so I went with a low-profile underglow kit with white LEDs and no animation features. I mounted the strips snug against the underbody using 3M VHB tape and zip ties for extra security, routed the wiring cleanly to the battery and fuse box, and used a Bluetooth controller for full control from my phone.
I only activate the lights when parked, cruising slowly through car meets, or pulling into my driveway after dark. That way, I get the style without risking a ticket.
Best LED Underglow Kits That Are Daily-Driver Friendly
Here are some kits I recommend that strike the balance between style and legality:
1. OPT7 Aura Pro LED Underglow Kit
Why I Like It:
It’s bright, well-built, and has one of the cleanest app interfaces out there. You can customize colors, but it also comes with a “Legal Mode” that locks the lights to a soft white or amber.
Pros:
- Water-resistant and road-tested
- Easy app control
- “Stealth mode” for daily use
Cons:
- Slightly pricier than others
- Wiring harness is bulky
2. Xprite Car Underglow Neon Accent Lighting Kit
Why I Like It:
It’s a solid budget choice that still includes all the basic features. You get a simple remote control, good mounting hardware, and decent brightness.
Pros:
- Budget-friendly
- Good brightness
- Easy install
Cons:
- Limited color accuracy
- Remote range isn’t great
3. LEDGlow Slimline Underglow Kit
Why I Like It:
Designed with discretion in mind. It uses thinner LED bars that are less visible during the day and are easy to tuck away if you’re trying to keep it low-key.
Pros:
- Slim, discreet design
- White-only option available
- Legal-friendly patterns
Cons:
- Not as bright as full-size kits
- Limited color options

Tips for a Safe and Legal Install
Here’s what I learned from installing mine:
- Use a fused connection to avoid draining your battery
- Tuck wiring away from moving parts and heat sources
- Choose an app-controlled kit with dimming and white light options
- Use zip ties and adhesive together for extra durability
- Keep colors neutral if you plan to leave it on while driving
Final Thoughts
Underglow is one of the most satisfying visual mods you can add, even on a budget. And if you do it right, it’s totally fine for daily use—just be smart about your color choices, brightness levels, and when you use it.
As someone who drives a lot and still wants to enjoy a little flair after sunset, I’ve found that a legal, subtle underglow setup adds personality without causing problems.
