led h4 bulb to long for stock housing

[Robm422]

So after returning the HID kit I had bought, I bought a pair of H4 Led cree bulbs. When i installed it, I discovered that the bulb was about a 1/2 too long for the housing. The bulb comes with the ballast attached to the back of it. I turned it on and it was really bright, so I like to keep the bulbs.
Does anyone know if their's a way to make the housing longer/ deeper?? I thought about drilling out the back of the housing and letting the ballast stick out the back a bit, but just wondering if anybody has ran into this and what they did....

Unfortunately while you might be able to make that work you will most likely not be happy with the result. If the housing is not reasonably sealed it will get moisture/dust in it and reduce light output plus since the elements on the LED are not in same location or orientation as the element in a H4 bulb the optics will be all wrong.
