You're kidding, right? I'm not talking about the wattage carried by the wire, I'm talking about the dielectric strength of the insulation. Why do you think they use 5kv cable for neons?
Also, it is extremely rare to find HID high beams. They take too long to heat up. Since most people only use their high beams for short periods of time, HIDs wouldn't work very well. Even many factory HID installs use regular filament bulbs for high beam.
