Understanding the process of wiring

If 14 gauge wire can supply 120 volts to three 60 watt light bulbs

Then why do some vehicles require 3 power wires for one light bulb ( 2 for HID lighting for the ballast and one for the parking light ) with 2 grounds, couldn't they just use one ground and one supply that could hold the current, then split at the connector for the internals ?
