thankyou for the kind words sir really appreciates that
as faar as ur query regarding hids is concerned then sir mark my words and that advise is for everyone whoever wants to go for HIDS that whenever one goes and buy himself nice pair of hid kit including hid bulbs and ballasts then he must also buy pair of plug n play projectors that will fit in reflector housing what these projectors do they will keep the beam low and make nice cut off beam and not disturb oncomming drivers guarantee .. not the halogen projectors but bi-xenon projectors that give both hi/low function .. from last week i was observing and reading many articles on google and internet and updating my knowledge regarding how to make my hids more effective , bright and down to the road .. then ive came across this thread and it TOTALLY changed my views regarding hids plz find some spare time to read it and i guarantee u wont dissapoint and yes ive done this all myself piece of cake if ur a good retro fitter :D.. heres my inspirational thread link
