It knows what the car is doing
It plugs into the same socket under your dash that a mechanic uses, on most cars built since 2008. If you have an aftermarket engine computer, it can read that instead.
Automotive lighting
Your car already knows how fast the engine is turning, how fast you are going and how hard you are pressing the throttle. CARGB listens in and makes your lights follow it, live. Every feature is included, nothing is locked behind an upgrade, and firmware updates are free for life.

Tubes under the sills in the nineties. The Fast and the Furious. Need for Speed Underground. A colour you picked once, in a shop, and then lived with.
Fast forward a few decades and the technology has moved on rather a lot. Now you change the colour whenever you like, run patterns that move along the car, and — the part that did not exist back then — have the lighting respond to what the car is actually doing. Revs, speed, braking, gear changes.

There is no paid tier of features and no subscription. Every unit ships with full functionality.
From your phone or a laptop. The controller you buy today keeps gaining new lighting patterns and support for more cars.
A small sealed box that lives behind your dash. CARGB comes with the cable that plugs it into your car, and you set it up from your phone or a laptop — there is nothing to solder and no app subscription.
Configured over USB-C or Bluetooth · Connectors moulded into the case. In the box: USB-C cable · Power, ground and CAN cable, wired to the OBDII port, with a switch on the power wire.
