To answer all questions in this string so far...the glass or "reflective" housing does not diminish the halo effect. I have a set of Angel Eyes on my J that I did myself and they work perfectly.
Tap into your parking lights. Don't make them blinkers.
Don't paint your housings black because then you ruin the chrome concept of your J. Stay with your luxury apperance...don't permenantly modify your car that much just for a set of lights.
Check out my car and send my ya'lls picks to...later!
