White lights are not going to blind others ... Infact,Whatever the color you choose to put in them ,They will not blind others ,They are HID projectors ,And hidz are meant to be used in this housing 
So colour preference is upto you ..... My projectors are equipped with 5000K color temperature which having white light but with slightly yellow touch,You can say its the best of both world temperature 
I will post both high and low output of these projectors to get you guys an idea how they perform ........ Ofcourse they are Projectors ,They are meant to give you the desire results from HID ... Mine lights are well focused and having slopes wherever I required ... However ,whenever i need to change the lights direction .... It will works with adjuster 
They are and will be at the same point even you hit the road or drives on a bumpy road
