@luckybilal, i don't think so these bulbs will improve your visibility at all.
I have used both Philips Blue vision and Diamond Vision. Interestingly Philips Blue vision are the only 4700K rated bulbs which are legal in germany in HID like category.
Diamond Vision has too low lumen output that the are not legal here, i had to source them from UK to tryout. After all sort of testing, i ended up at the conclusion that coated bulbs somehow are not that practical to use specially in our environment where you are always getting blind from oncoming traffic.
I have switched to HID's now and my experience is with halogens you are better off with standard bulbs. However i agree you will have better road sign illumination and off course they will look sick!!
