bouncing is not because of the headlight itself, its because of the brackets that hold the light in.
That would be overkill
Don't think any ebay headlights get much thought personally
Other thoughts:
-personal experience tells me that those high beams will suck cause they are using some flashlight reflectors.
-those halo rings will probably be weak and probably won't fully light the whole ring evenly
-Supposedly they are H1 projectors, which is a step up from previous ebay headlight models which all used fog h3 bulbs. Interested in seeing output and cutoff. Again you get what you paid for, granted these are $300 a real projector set costs $200. Think about it. There is probably $40 worth of material here.
In the end...I'll bee keeping my projector retro but I am interested in seeing how these work out for you guys.
