The problem is that the optical tube is not placed correctly. I was playing with it yesterday. If the tube's angle is just a bit off, the light will apear to fade or have a halo appearance.

The solution is to remove the door panel, loosen the screws that hold the optical rod, and turn it slowly until the light is bright and clear. Yes, you will need to ajust it in a dark garage so you can see the light.
