Stevensnj is correct. The headlight housing is what dictates the "throw" of light. Its problematic with the HIDs and the stock housing because since they are diffused, the light is "thrown" in the same direction as it would factory but at a much higher intensity, hence the name HID. I'm not sure if there is a specific amount of lumens until you should switch to projector lenses but you can always experiment on your own. Increase the number of lumens until you have had enough peopleyou off.
right, so do the led bulbs like this one also require projector headlight lenses? that is the question I am trying to answer.
