Indeed, glare is light, but it is scattered light (straylight). When you get dazzled the intraocular scattering causes veil luminance on the retina's surface, which reduces image contrast which in turn impairs vision. It is not exclusively reflected, it can come from an emitting source such as the sun (or a HID headlight ;) ).

Any answers folks?

As you can tell, I'm not exactly a fan of retro-fit HIDs so I obviously I haven't fitted them and can't answer directly. However, I've found one post buried deep in an old thread that probably has the answer/info you're looking for...

It does involve some irreversible butchery of the main beam bulb holder/connector.

What I'd also add is that, because of the slow 'warm-up' time of HIDs, you will need to do the mod that keeps dip beam on all the time regardless of switch position. If you do not do this mod you will end up with a few seconds of very poor lighting every time you flick from dip to main or vice-versa as the HIDs get up to temperature.

Sorry can't help with modifying the mount. I just upgrade the standard bulbs to Narva 110% Intense H7 bulbs, which helped, then ended up fitting spot lights down the track anyway.
( The bulbs are still 55watt, I think the reason the main & dip are both 55 watt is so if one blows out in the medal of nowhere then you just use the one working one left in either light till you can get a replacement ? )
