I can not at all say so much about it. I bought them for my motorcycle and I at night not so much driving, I play the brightness - goofy that I just so say -. eig not matter ... I read again and again, the asphalt, the light " picks up "and you will no longer recognize the road properly. just in case of rain ... so maybe that's true, but really minimal. During the day you really can see the bluish tone is not strong. at night, I find it quite well. it is not as blue as in a proper xenon lamp, but that's logical ...'m the last time next to a car driven with xenon and have the light on the floor followed. So nen big difference I really have not seen ... and at such a price you can not complain much ... Just looking to buy and look obs fit. I suck it and I'll buy it again. to the life I can not say anything ... Conclusion: no sau horny, but cool;)
