Here is a solution to a common problem. For those of us that have halo lights controlled by remote, we cannot see what the halos are doing unless we are standing in front of them with remote in hand.. wouldn't it be nice to know exactly which mode the halos are in from inside the cockpit??
The light mimics whatever the halos are doing, including dimming from 100%
Here's how its wired:
I used a 5mm / 12 volt LED light.
I used spare 2 lead / 20 gauge wire that I had on hand, and cut a piece long enough to reach
from the point of the LED indicator light to the wiring between the RF controller Unit and the Halo LEDs.
For the position I chose for the light, I taped off, and measured out the center for my drilling position. I needed to remove the infotainment center, to do so, loosen the 4 screws in each corner that holds the faceplate, once removed you can pull out the infotainment system and unplug the 2 plugins on the back side of the system. don't worry, the wires are labeled, as well as the back of the system. ( I reinstalled the faceplate, just for placement, while measuring for center).
3/16 drill bit for the hole
I slipped on appropriate sized heat shrink wrap onto each lead coming from LED Indicator light, soldered the LED indicator leads into the spare wire leads, keeping the positive and negative leads common. Then slid the heat shrink down over my solders and applied heat.Test your soldered wires, by holding corresponding +/- leads to any battery that has a separate +/- posts, if the LED lights up, your good to go. I used a 6 volt battery to test.
With the indicator light installed into place, I ran the two lead wires down, spliced and butted into the OEM halo wiring between the Halo RF Controller Unit and the halo lights.
(A lot of people do not like butt connectors, however when I use butt connectors, I use Dielectric Grease to stop any oxidization of the two connection points)
The wiring coming out of my RF Controller Unit for positive is RED, the negative is RED and BLACK (funny thing about the halos, if power is interrupted to the controller unit, when power is re-established the halos will be on, as the circuit will be hot).
Finished by wrapping wires with electrical tape, then adding loom over wires.
*Thanks to @rabtech for supplying the indicator light for this project, and I didn't have to give up a rocker switch using this method*
Luckily, we only killed the battery once. And it wasnt long after that, steve installed a big battery.
and we (steve, i have been sick with sinuses) just did not want to chance making a small project turning into a big project that invovled replacing halos all together... 
I took the blue LED out of a crappie old 12v plug in El Cheap-O interior accent light purchased ages ago and sitting in my junk bin.
