Well mine have been in for about 3 days and I've aligned them myself, I commute down country lanes to work at 6am and 7pm and I can honestly say that I do not need a high beam, and I can see what the road looks like further than just in front of me.

Just gotta know how to align them properly for best results and not to blind oncoming drivers, if you are prepared to swap the bulbs over for your MOT and save £150 quid on a set of bi xenons I'd recommend them to anyone!

Obviously I've never been in your car, or driven towards it, so I could be completely wrong, but...

I don't really see how that can be... The standard H4 bulb has a shield blocking off the light in one direction from the dipped filament. That combined with the shape of the reflector gives a clear cut-off pattern in the light, sloping up towards the left on a RHD car. Above that cutoff there's virtually no light, so you can't see, but you don't dazzle. Below that there's lots of light so you can see, but do dazzle. They're aligned so that the cut-off's not too far up the road in front of you, so that even on gentle crests the lit area doesn't shine on other car's windscreens.

The main beam has no cut-off at all. The light just gets gradually dimmer as it reaches further into the distance. That means you can see a long way ahead, but light will shine into oncoming cars, dazzling them.

Does your HID conversion have a cut-off? If not, then I don't see how it can avoid blinding oncoming cars. If it does, then surely you won't be able to see any further up the road than that cut-off (ie worse visibility than the standard H4 main beam).

But then I generally end up being proved wrong....

AJB, I'd concur, having just fitted Powerbulbs' 50% brighter units (Actually Philips bulbs, supplied buy 1 pack get one free, plus the Philips sidelight bulbs replacing almost black standard bulbs, which was a lot of bulbs for 20 quid). I've only got a few yards extra on dip, but main beam range has almost doubled (based on vanishing point of non-reflective verge in dark but dry conditions).
