Installation
Nothing gets cut. Nothing gets drilled. Every part you need is in the box — here's exactly what you're signing up for.
Phase one — wire it up
Hook the wiring harness to your battery, following the diagram in the box. No splicing into factory wiring.
Join the controller to the harness and extension, then mount it in the engine bay with the included zip ties or tape. Keep all wiring clear of moving and hot components.
Power up and confirm every strip lights correctly — before the adhesive goes anywhere. Two minutes here saves you peeling a strip off later.
Run the switch through an existing firewall grommet — no drilling — and mount it somewhere you can reach from the driver's seat. This switch is what cuts power so the lights can't drain your battery. It's the most important step in the install.
Phase two — mount it
Lay the strips out under the car and confirm the direction of each one before anything sticks. Dry-fit first, always.
Clean every mounting area thoroughly with the included prep pads. This is what decides whether the strips stay on — road grime is the only thing that beats the adhesive.
Press each strip into place and hold firm pressure to activate the 3M adhesive. Use the extension cables wherever you need the extra reach. Then go find somewhere dark.

Light Up My RideReal installs
Solid Colors · Sedan/CoupeThe app is super easy to use and the colors are crazy bright. I usually keep it on solid green to match the DRLs but the chasing patterns are sick when I'm parked. Install was easier than I expected too.
Solid Colors · SUVI wanted something that actually stood out without looking cheap and this was exactly it. The flow modes at night are insane and people ask me where I got them every time I hit a meet. Bright, clean, and way better quality than the Amazon kit I had before.
Flow Lighting · Sedan/CoupeHonestly one of the best mods I've done for the money. Everything synced up perfectly in the app and the colors are super smooth. Been through rain a bunch of times already with no issues.
Solid Color · Sedan/CoupeI went with solid ice blue and it matches the car perfectly. Super clean look without being over the top. Install took me a couple hours in my garage and everything worked first try.
Flow Lighting · Sedan/CoupeWorks great after a year still bright with no flickering, and customer service is amazing I had an issue that was my own fault and they helped me so much

Every question people ask before they buy — answered before you have to ask it.
Real customer installThe strips mount to your undercarriage, so they take everything the road does. That's what they're engineered for.
Three kit sizes — Sedan/Coupe, SUV, Truck. If it runs a standard 12V system, it fits. No vehicle-specific parts.
3M automotive adhesive plus included mounting clips. It stays where you put it.
Wires to your 12V with an in-cabin kill switch included. Flip it off and the lights draw nothing — no parasitic drain, no dead battery Monday morning.

Solid Colors ships with an in-line remote. Flow Lighting adds phone app control and music-reactive sync.
Nothing is spliced into factory wiring or bodywork. Fully reversible.
Mostly yes — but we'd rather tell you the truth than sell you a ticket. Underglow is legal in most states with restrictions.
Your kit does every color, including a steady white mode — so you can stay compliant on the road and light it up when you park. Check your state's rules →

Light Up My RideStraight answers
The questions people actually email us — answered without the runaround.
Short version: Solid if you want one clean color and the brightest possible output. Flow if you want the light show — it adds phone app control, music-reactive sync and flowing chase effects.
Both are equally waterproof, install the same way, and carry the same guarantee. Flow runs $10 more per kit size.
One honest note: the flowing and chase effects are the part most states restrict while driving — so Flow earns its money at meets, shows and parked. If you only ever want a steady color on the road, Solid does that job for less.
It depends where you drive, and we'd rather you know before you buy than find out from an officer.
Most states allow underglow with restrictions on color and motion. Nearly everywhere, three rules hold: no red, no blue (both read as emergency vehicles), and nothing flashing or chasing while the car is moving.
Stricter states. Massachusetts, Connecticut, Pennsylvania, Virginia, Michigan, Minnesota, Illinois, Maine and Washington restrict underglow on public roads — several still allow it parked on private property or at shows. New York permits white only.
Your kit does every color including a steady white mode, so you can run compliant on the road and light it up when you park. Violations are typically a civil fix-it ticket — but cities can be stricter than the state, so check both.
