Typically, cars built with HIDs in mind have a sort of blind built in inside the housing to direct the light appropriately. Also, it's possible that the bulbs just aren't positioned correctly within the housing to direct the light appropriately. Much like trying to burn stuff with a magnifying glass. The magnifying glass and the sun have to be positioned just right.
My best suggestion is to buy a great set of halogen bulbs (Sylvania zXe) and if it still bugs you, invest in an LED Light bar.
