First aiming headlights at the factory. though I believe it is done. may not be all that effective as when you start to load up the car the angle of the dangle changes. For example you put your grossly overweight relative in the back seat the lights now aim a tad higher. You put your portable recording studio in the trunk (yes I actually have one of those) the lights aim a bit higher.
18 Watts of High efficiency LED's is a LOT of light. 3 watts as I recall is what my 1200 lumen flashlight eats. and that's about the same as a 100 watt incandescent lamp.
Oh that I use 18 watt "fog" lights
