A general note, LED bulbs in a reflector will never have the right pattern, same for HID bulbs in reflectors. Those will only have the right pattern in a projector style lens (and even then, it needs to be made for HID/LED, some of the older ones are dialed in for incandescent bulbs). That's not to say it won't work, but it will scatter light where you don't need it, possibly into oncoming driver's eyes, and be less efficient at putting light where you need it. Most LED complete housings are going to have decent patterns, but rarely do they look stock.
And a note about light color, brighter white/blue light helps with pinpoint vision, yellower light helps with broad vision. Blue shrinks the pupils and sharpens focus, but allows less light in (almost like wearing lightly shaded sunglasses). Yellow/red light dialates the pupils, which lets in more light but doesn't focus as well. In driving, this equates to being able to tell it was a german shepherd with a red collar that ran out in front of you 50 feet away with blue light, but being able to see that there is a dog on the side of the road at 100 feet with yellow light. Most municipalities are moving away from the blue street lights and towards yellower LED's for those reasons.
