Yep, should be in LKM. That's where Carly reads it. I wired my cheap riced out ebay halos to do the same thing you are going for. Factory halos have terrible brightness due to the light pipe design being only able to transfer limited lighting around the rings.

So right now, when do your halos turn on? Only after turning on the headlights or sidemarkers?
