Re: Headlight replacement H7 motovision bulbs
Uuuuuum. Even though the bulb bases are the same, H7, the rumor I remember is that because HID bulbs do not produce light in the exact same place as the bulb your are replacing, and our headlights focus the light, your beam will not be focused (mine isn't). Mine is brighter, especially good at illuminating road signs, but I rely upon my PIAAs to fill in the close to me areas.
I have seen spacer to try and make it better. And, I've seen claims that the knock-off HID bulbs have less illumination that Phillips. Phillips does not make a H7 base, so the bulb's base has to be modified. And, the Phillips socket is different than the H7's, so one needs a pig tail designed for the Phillips bulb.
Doing that conversion is on my list of winter projects for when I have the nose cone off.
I've also seen rumors that the clone ballast-starters are less than ones made in Germany. There is however a current production ballast close to the Phillips ones.
If you scan enough, maybe using HID projectors, you'll find these rumor mills.
