I have been searching forever and can't seem to find any info about the dimensions of the OEM headlights. I'm looking to buy halo rings to do something custom instead of buying a halo kit like Oracle.

What size (preferably in mm) halo rings do I need to get? Main headlight and the smaller parking lights that is.

The closest I have come to taking measurements without having to bake and open the headlights to measure them are:
~4inches for the parking lights and ~7 inches for the headlights.

Does this sound correct..? If not, what are the exact dimensions?

And since the headlights need such big halo rings (over 7in diameter), can I even find rings bigger than 160mm to fit them?

Thanks for any help.
