One other thought this is independent of the install posts above. This is an observation, not a perceived problem, and I wanted to get your thoughts.
The original H4 shines light upward in LOW beam mode only, and shines light both upward and downward in HIGH beam mode. These xenons, on the other hand, shine light upward in either mode. The big shield has a hole in it as can be seen above, which I would have thought allowed the light to escape downward in HIGH beam mode, but it doesn't!! In fact, the light can never go downward, because the hole in the shield is too close to the solenoid end, and the arc never gets close enough to it to allow the light out. Does anybody have any idea why? Why didn't they allow the hole in the shield to be closer to the end so light can get through it in high beam mode?
