LEDs can be seen for a considerable distance, and look intense from a long way off. But they have a beam throw that sucks majorly. To get a beam throw from LED lights that comes anywhere close to an incandesant bulb, you'de have to stack a lot of LEDs in an array. By then, the power savings LEDs are known for goes up in smoke. You'de been better off just running the halogen.
Comparing LED headlights to halogens and HIDs is like comparing pinpricks to a broadsword wound.
