I still have them installed but I think the kit I bought is just really cheap chinese crap. It does effectively reduce your headlight electrical consumption by more than 50% but the beam pattern is fuzzy and doesn't have a real horizontal cutoff like you mean.
It really just spread the light beam into pretty much all directions exept where you really want it, in our case, the road. You need to reajust the headlights so you don't blind people. Also there is not much difference between low and high beam. You can see the difference in really dark areas but otherwise you won't see the real difference.
So I cannot recommand those LED headlights kits unless what you wan't is purely reduced electricity consumption. They are like 25w each instead of 55w each for H4/9003.
The bright white light color is really nice tho compared to the yellowish stock halogen bulbs :
