Is there a reason the hids get brighter when I push the lever forward to turn on my high beams.
In bi-xenons both the low and high beam are produced by the same xenon bulb. The difference between these is, that when you only have the low beam on, a shutter masks off the top part of the light beam, so it only shines right in front of you, and when you put on the high beam, the shutter gets completely out of the way, allowing the full beam to exit straight out forward.
So, the hid bulb getting apparently brighter (observed from outside of the headlight assembly) with high beams on is completely normal. And the bulb is not only getting brighter, but it is now emitting light in a different, broader and more straight out pattern than it is when only the low beam is on.
If your headlight appears dim, that might be because the projector is dirty. If the dirt/dust is on the backside of the projector lens, you might be able to clean it by taking out the bulb and carefully reaching in with a microfiber cloth on a stick or something. However, if it's on the outer side of the lens (which you can see when you're looking at the headlight when standing in front of the car), then you can't really do much. I mean you can try to take the headlight assembly apart by melting the glue that holds the front and back parts together, to open it up, but that's not an easy job and you can easily damage stuff. In this case I personally would just leave it as it is, as long as it's still producing a usable amount of light.
