I have xenons on my Octy, but I went the proper route and fitted them with OEM projector housings. It cost more but gave the desired result without blinding everyone else.

Nice one! Someone who is doing the job properly.

The problem with discharge lamps is nothing to do with alignment, but everything to do with glare and excess light scatter. A lot of the people on this thread keep going on about alignment, when in fact they mean glare.

Even if your discharge lights are perfectly aligned on a proper beam-setter, there will still be loads of extra light 'scattered' from the light in all directions. Halogen does the same, but because discharge lamps have such a higher intensity, more light is scattered, and this is what glare is, and what *****s everyone off.

That is why proper OEM discharge lights use projectors instead of reflectors. Because all the light has to go through the lens, the light pattern has a perfect, pin-sharp cutoff line that reflector based designs just can't produce.

This is a pic of a projector cut-off:

And the same again, but in a reflector housing designed for haogen bulbs:

Can you see how the projector pic has no excess light, whereas the halogen unit is all over the shop?

And, I'm not some "Old C@ck", as someone politely put it, I'm 24 FFS!

Remember someone following me home on a busy country lane one night with badly fitted aftermarket HID's. No possibility of overtaking to get away from the annoying glare which was giving me a headache, even with a dipped mirror. After 5 miles, I felt like stopping the guy and sticking his head into one of them, so he could see better, of course.

This may make me sound like a ch@v, but I think those look cool. Certainly different.

I gre up with Tron, so it reminds me of a light cycle, as someone else commented on the vid.
