I can't decide between these two bulbs: Philips Blue Vision and the Philips X-Treme Vision I currently have standard OEM bulbs and find the lighting to the sides less than adequate. I love the slight blue tinge of Xenon's and I really like the projected light colour. What I don't want is a bulb which isn't as good as my stock ones - or one that is going to fail fast. Does anyone have experience with both of these? Philips don't seem to be providing me with the life expectancy, I am after a year of day to day normal use minimum really.
