as mentioned on the other page birds you were reported because your car is not stock, ie after market exhaust and front mount etc so it is reasonable for the police to conclude your car may not comply with the regulations and this is grounds enough for the notice.
as for the hids they are not illegal becuase of there brightness, as far as i know i think its 4000 or 4300k are the only legal hids, but they must be factory fitted and comply with the regulations. there are no legal aftermarket kits unless you go to the effort of washers and or auto levelling but then your car still wouldnt have been ADR approved to have them which will then find you in the same boat you are now..
also having had an aftermarket hid kit fitted to my old honda euro which was the standard model so non hid from factory.. they use to blind everyone becuase the were not fitted/levelled properly and i can say it shits me when cars have them and they havent been put in properly and im gettin dazzled the whole time they are behind/coming towards me
sucks i hear ya
if ya want try tidd brothers hudson road spotswood did my exhaust test there was cheap as.. might be too far for u though
