Hello. I recently sourced a pair of philips xtreme vision h4 from UK, but i have removed them since they produce yellowish light, whereas i want whitish light for styling. Thus, after some research, i am confused between two options, namely philips crystal vision and diamond vision. I own a black honda city12, and i am really not sure which of the two would be the better option. Crystal Vision bulbs are 4300k while diamond vision is 5000k. I have already wasted money on the xtreme vision h4s since i wasn't aware of the other two, so, this time i think it would be wiser to get opinions from fellow pakwheelers. This is my first thread, and I'm pretty sure you guys will guide me well. 
Regards.
