ok for a start 6500K should be pure white with no hint of blue, however most people who arnt used to looking at varied colour tempretures think they have blue tints because they are too used to looking at normal globes.
Glare is a serious issue and I had to face my lights directly at the road infront of me to stop people high-beaming me. I have now ordered 4300K globes to replace my old globes so I can hopefully have less glare and therfore tilt them to a usefull angle again.
That link is not for a direct plug and play model, the proper kits have a plug that goes into the socket that previously would plug into the back of your H4 globe.
The postage is steep but I am sure you have already seen it.
Try this product instead:
just select the colour you want and the globe type at the bottom, you want a H4-2
this is a fully plug in kit
