At all the rallies, all the outdoor shows, all the truck shows, there is ALWAYS one thing in common when the lights go down..............HID lamps rock. So does the price. I don't have them, but if I was to doll out some dosh for a much wanted accessory, HID lamps would be at the top of my list. Damn, they are bright. And I am a lighting guy, day in, day out. Far, far far, superior to other "normal" headlights to the factor of at least 3:1, sometimes 6:1 on light per watt. That is to say, for the power they draw, they reign supreme. Way above incandescent, way above Halogen or Xelogen, way above LED. If you want to drop the coin, they will reward you.
That said, it sure would be nice to have pencil beams on your roof with cornering lights outside of them, then headlights as the Eurobeam. That pretty much would feed the family. I don't know really what I mean by that, but it sounds about right. Cheers.
