Quick headlight question

Nope - those are for halogen headlights not xenon, so if you wanted these you would have to ditch the xenon bulbs for halogen.
 
I'm not sure exactly but the heat generated by a xenon bulb is pretty damn high so not sure if the internals are man enough (including the lens cover). I wouldn't risk £100 on it! If your lenses need smartening up there are threads that describe how you can polish them up. Also people have replaced the lens covers before although it's a fiddly job from what I've read.
 
They are not made for HID bulbs, but they will handle it.
HID bulbs do not run hotter than Halogen bulbs.

But I heard many times about people complaining about this TYC / DEPO headlights not giving a good light output.
It would be a better choice to install the Original HELLA headlights.

And then also you can chose the Hella halogen headlight (H7) and the Hella Xenon headlights (D2S).
The price will be the same aprox, since the headlight is just the same but with a different bulb holder.
