If anyone is curious, here's how I mounted the Halos. I took a lighter to a thumb tack and melted holes in the shroud on the outside of the rim. One hole at 12 O'clock, one at 4:30\5, and one at 6:30\7...just evenly space 3 holes. Then I took the twisty ties that come from garbage bags, burned off the paper(Fire!!!!) so it was very thin, bare wire, then used it to strap down the halo. No glue, no dripping, no failing, no discoloration, did I mention reliable? Here's some pics:
Wire stick through hole:
All three, LOOSE. Slowly tighten each one after you start all three, it doesn't have to be very tight at all.
I grabbed them from the back side with some needle nose pliers and twisted them to tighten them down, like I said it doesn't take much. Just to the point where the halo won't move anymore. Then use wire cutters to cut off the excess wire, and fold it back into the corner:
Now I just need to drill a hole in the housing, run the wires and put it all back together. Then I might actually try and aim them during the day, lol. They are pretty bright, so who knows.
