I already have 4" Optilux Hella 6000k HID driving beam on bumper and LOVE it, should I get it also for windshield? they were a bargain for the performance..I'd love it, but I have a black JK and would there be too much glare from the hood? and on windshield mirror mounts would they show alot into the distance?

 

They are a notoriously glare-producing light.
A-pillar lights work better with a tight focus. A Fuego or Lightforce, for instance.
