My Oracle halos have been dying a little along (multiple LEDs out) for the past year so I decided to try some Diode Dynamics switchback halos. I used 160mm and cut the top so I could spread them out and make them fit correctly. Turned out great.
I have the amber as turn signals but also ran the wire out with a quick connect on it so if I get tired of the halo blinking I can just make it go out when the turn signal comes on like the newer models.
Here is a video of the turn signals working.
And below is the halos only on.
