Agreed! Having just the highs leaves a noticeable dark spot in front of the vehicle. Having the highs and fogs on at the same time would be legendary.
I wish someone smarter than myself could figure out how to do this without some cumbersome workaround - obviously I want to keep my factory fog indicator and switch working as normal.
And true, the difference between HID high and low and Halogen high and low is not as distinct. However, I re-aimed by HIDs lower, and this made a major difference (the highs aren't pointing out into space.
One other big reason to get bi-xenon is that when someone flashes you because your lights are so bright (doesn't happen all that often, but it happens), you can hit-em back with double brightness.
