"notice how the light shines up"
That gives you low beam, to get a high beam one needs to have the light shining down with possibly the light shining up as well to give a better around coverage. without light shining down into the bottom of the reflector you will not get much of high beam illumination. the better bulbs have at least 2, some 4, LED's - 2 low - on top, 2 high - on bottom. of a bulb assembly.
