I'm sorry to disappoint you gentlemen, but these will not work anywhere near as good as an HID setup would in our housings.
LEDs simply do not have the needed lighting angles for a halogen/HID projector bowl to properly focus the light into a nice sharp cutoff, with good distance. All these things will do is glare like hell to oncoming traffic, and they will mostly flood the foreground of the car with light and not much in the distance(where you want light).
