Underglow lights turn a plain car into something eye-catching at night. They come as LED strips, wired kits, and RGB modules that let you pick colors, set patterns, and sync lights to music or driving. We focus on easy installs, durable weatherproofing, and bright, even light that won’t drain your battery.
The key things to watch are waterproof rating, power draw, mounting method, and whether the kit is legal where you drive. Poor waterproofing or weak adhesive can mean lights fall off; excessive power draw can kill a battery; and certain colors or flashing modes can get you a ticket in some areas. We tested multiple kits for brightness, durability, ease of install, and legal flexibility to find the ones that give the best look without headaches.

Best Underglow Lights for Cars
We tested and compared top underglow kits for durability, brightness, and ease of install. Below is our list of the best underglow lights to help you pick a reliable option for style and safety.
Govee Underglow Car Lights
We recommend this kit if you want bright, colorful underglow that’s easy to install and control from your phone.
Pros
- Rich color options and fun scene modes.
- Simple app control and music sync that actually responds.
- Waterproof sleeve and solid mounting accessories.
Cons
- Not compatible with cigarette lighter power — hardwire needed.
- Strips are a bit stiff; avoid sharp bends or pulling.
- App features can be overwhelming at first.
We installed the Govee set on a weekend and liked how fast the colors came to life. The RGBIC effects let us pick different colors along one strip, and the photo-pick feature matched tones from images surprisingly well.
Driving around, the music sync added a lively vibe. We tested both Soft and Dynamic modes and saw clear, steady reactions to bass and beats when using the phone mic.
Mounting felt practical but required care. The adhesives held on painted metal, and the clips added security, yet we were careful not to twist or kink the strips during placement.
Powering the kit meant hardwiring to DC 12–24V; the manual warns against the cigarette lighter. Once power was sorted, the app stayed stable and offered many presets we used for nightly drives.
Overall, this kit balances vivid effects, ease of use, and weather protection, though buyers should plan for a proper power connection and gentle handling during install.

Cons
- App can be a bit clunky compared with simpler remotes.
- Heavier and bulkier than flexible strip kits.
- Pricier than basic underglow sets.
We installed these on a crew cab pickup and liked how stout the bars felt when we handled them. The aluminum housing makes the lights feel like they belong under a truck, not like a toy. Mounting hardware held tight during our test drive.
Using the app and the remote together felt handy. The music-sync brought a fun effect at low speeds, though the app took a couple tries to pair smoothly. We appreciated the range of colors and the steady brightness at night.
Wiring was straightforward with the included harness and inline fuse, and the bars stayed put over bumpy roads. If you want something lightweight or wish to save money, a flexible strip kit might be better, but for durability and strong light output this felt like a professional upgrade.
Buying Guide
We look for lights that match our car and driving needs. Measure the area under the vehicle and check clearance to avoid contact with road debris. Choose flexible strips for curved sections and rigid bars for straight mounts.
We check brightness and color options. Brightness is measured in lumens; higher lumens mean more light but can draw more power. Look for RGB or multi-color options if we want color control, and test modes like strobe or fade for safety and style.
We examine build quality and weather resistance. Pick lights rated at least IP67 for water and dust protection. Durable housing and silicone or PVC coating help resist salt and gravel on winter roads.
We review power and installation methods. Hardwire kits give a clean install but need basic wiring skill. Plug-and-play or battery-powered kits are easier for renters. Ensure the kit includes proper fuses and waterproof connectors.
We consider control and compatibility. Choose controllers that work with our phone or a remote for easier color changes. Check that the controller supports multiple zones if we want different colors in separate areas.
We prioritize legal and safety factors. Confirm local laws on vehicle lighting at government sites like state DMV pages or the Federal Highway Administration to avoid fines. Also inspect mounting brackets and wiring to keep lights from coming loose while driving.

FAQS
Are underglow lights legal?
Laws vary by state and country. We check local rules before installing and advise avoiding flashing colors that mimic emergency vehicles.
Will underglow damage my car?
No, not if installed correctly. We use pads, clips, or screws on non-painted areas and route wiring away from heat and moving parts.
How hard is installation?
Installation ranges from easy to moderate. We can hardwire to your battery or use a plug-and-play kit. Basic tools and patience usually suffice.
How long do the lights last?
Lifespan depends on quality and use. LED strips often last 20,000–50,000 hours. Moisture and poor wiring shorten life.
Can I change colors and patterns?
Yes. Many kits include remote control or app control. We recommend RGB or RGBW kits for more color options and white light.
Do underglow lights use much power?
They use little power compared to headlights. We estimate 1–5 amps depending on brightness and the number of strips.
How do we keep them waterproof?
We pick IP67 or IP68 rated strips for wet conditions. Sealed connectors and silicone conformal coating help protect wiring.
What about safety and visibility?
Underglow adds style but not road lighting. We keep head and tail lights for safety and use underglow only as accent lighting.
Conclusion
We picked lights that balance brightness, durability, and easy install. Each option fits different budgets and goals, so we can match a kit to our needs without guesswork.
We value safety and legality, so we favor lights with clear wiring, solid waterproofing, and modes that let us avoid flashing patterns where illegal. Installing correctly keeps the lights working and prevents electrical trouble.
For budget builds, reliable single-color LED strips give strong looks with little fuss. For more control, RGB or app-controlled kits add color and effects, though they cost more and need extra care when routing wires.
We recommend checking local laws before buying. Many places restrict colors and flashing; using dimmer or interior-only modes can help keep us legal.
Quick checklist:
