I have used these bulbs a long time in my Ford Focus Mk1 facelift (H7 low beam, high beam H1) and can only positive things.
The light is great, wide and broad illumination.
The color of the light: these bulbs are not the typical strong blue colored Xenon lamps similar appearance! When looking into the headlights, the light is clear white and bright! On the street itself, it acts like normal light bulbs.
In projection headlights (headlight lens) of white effect is lost completely - as with almost all optics Xenon bulbs. Furthermore you should be aware!
