+1, Jasper. My philosophy for upgrading forward lighting is to increase the availiable light on the road in front without creating glare to oncoming traffic. This has been my rule of thumb since H4 headlight and halogen driving light upgrades since the 1970's.
That piece in the middle of the reflector is a glare shield, BTW.
