Why LED? Why would you expect an LED bulb to be brighter than an HID?
Given the fact that I have yet to see an H7 LED bulb without a big heat sink/fan assembly on it, I doubt it would work in the housing with the protective cover. The only real advantage an LED bulb has is the response time. But it's twice the price of a quality HID kit and not as bright. And the LED is directional where the HID has 360 degree light output so you may not get the same beam pattern with an LED.
