Pair over Bluetooth with the free Happy Lighting app — pick any fixed color from the wheel or a preset to match your paint, your wheels, your mood. No extra controller, no wiring.

Run dynamic effects — flow, breathing, gradient, chase — across the light bar for a rear end that's never static.

Slide to set animation speed and brightness until it's exactly the look you want.

Brake, tail, turn, and reverse always run their correct DOT colors. Color is show; the safety signal is business.

The digital bar is individually addressable — color flows along its length instead of the whole bar changing at once, so you get patterns a standard RGB bar can't run.

Driving, startup, and turn-signal modes carry far more animation patterns than RGB — chases, gradients, and traveling effects, selectable from the app's Mode list.

Run flowing, chasing, and segmented sequences across the bar, set speed and brightness, or let it auto-cycle the whole library.

Controlled by the same Starlight Running app and included remote, with master-and-slave cabling keeping both sides in sync.
