The problem with most of the less expensive LED headlights is that they don’t have any reflectors, thus the aim, cutoff, and optics of the light are limited to what can be achieved through only the output pattern of the individual LEDs, and as many have discovered that currently leaves much to be desired. There are better LED headlights out there that actually use fewer high powered leds with actual reflectors and optics, but be prepared to pay for them. Just as an example GE Nighthawk, Truck-Lite, JW Speaker, etc. LED replacement headlamps appear to have appropriate reflectors/optics to give a true low beam with an appropriate cutoff. (I have no experience with these bulbs, it just looks like it would actually work.) For those interested, there are a lot of good led headlight reviews and tests over on expedition portal, many of which have pictures of the beam patterns and show the cutoffs.
