hi, im interested with
> Osram Cool Blue Hyper (H4) or
> Philips X-treme Vision (H4).

but i need your advice:

1) which will project out white light on d road?
2) will the above cause glare to opposite cars?
3) which will give max performance visibility?
4) can the Philips Blue Vision Ultra W5W (T10) fitted to Vios 2012 sidelight headlamp/parking light? im not sure what is the size.

Thanks

finally decided to take up osram night breaker plus.. wait for the arrival :-)
thanks..
