Led headlight bulbs

I have seem some LED headlight bulbs for sale and was wondering does anybody use these or have any pics, how good are they?. I have LED sidelights but not headlights
 
Can't see then being much good to be honest. The latest CREE LED bulbs are pretty dam bright, but still rely on fancy magnifying lenses to get any range out of them. Can't see how that'd work with standard reflectors still in place
