Another option here is simply save up your nickels and dimes, and wait a while for the price of LED lamps to come down.
HIDs put out lots of light, but they usually have a "ballast" system on them as part of their start up, and this ballast is of course just something else to eventually fail, and leave you without a light when you really need it.
LEDs, on the other hand, have never needed a "ballast", are designed for super-long life (usually 50k hours or so), and are also designed to tolerate the high-vibration environment that motorcycle duty includes. They will generally draw less power than HIDs, as well. LEDs don't burn hot, either. And besides, they just look cool!
I know currently of at least 2 LED kits that are designed for motorcycle driving light duty (one of them even has a dimmer switch or dial), but they are pricey. It's simply a matter of time b4 the aftermarket world is offering more of these, at lower cost.
