Aside from changing the focus point from within the halogen lens, a single source LED driver isnt going to have all the light properly focused to actually throw it down the road. This is actually the same thing that happens when you put HID into a halogen reflector, light goes all over since you are changing the position of the light pattern/source. LEDs are great and have lots of potential and distance, IF they are designed properly, something that doesnt happen with tossing in a "LED bulb" into your housing. If you look at all the current OEM led headlamp systems, they are multi unit. Most companies are using an array of atleast 5 different optics to each LED driver set. This way they can focus each lens individually and position them all in a way that provide functional spreads of light. If you cover up any one of those units, you start to be dim spots in the headlight pattern, since the others are too focused in lighting one specific area. essentially what you would have with an LED like that in a halogen optic is an extreme amount of glare from unfocused light, TONS of immediate intensity, and a very short random range/width pattern. Photographing them can be tricky. i can make my HIDs look like they are WAY brighter then what they actually are and most cameras will go a default of a long exposure at night time even with a headlight source. this makes the photo seem like they are much brighter then they actually are.
Look back at the last picture where it is in that motorcycle light. TONS of light right off the bat but by the time its gotten to that crack thats maybe 10' in front of it theres nothing. All the light being captured there is from the cameras long shutter. if you really want good light you need to either a.) retrofit with proper optics b.) find some 9011/9012 HIR bulbs and run those. They wont have the color of HID, but the output is nearly identical.
