For the most part that'* correct. The problem is not the continuous current you need to run HIDs, as a 35W HID will use less power than a 55W Halogen. The biggest problem is lighting them. You need a surge of electricity to light an HID bulb (done by the ballast), and that split second puts a heavy strain on your wiring. My Bonneville has this problem severely, to the point where I've fried one of my ballasts on the fog lights. There simply isn't enough current running through the wires to start those bulbs, and they'll flicker when turned on till they get enough power to stay on.
Could be that I just got a really cheap or crappy set, but that'* what my experience has been. I still have to upgrade the power wiring.
