Since I'm a visitor to this section I'll be polite, and merely point out that retrofitting HID's into 'Incandescent' headlights is not a Good Thing and there are sound technical reasons why they will ALWAYS emit dangerous, distracting and downright annoying (read: Road-Rage) glare.
The specular nature of HID's is distracting at the best of times including when fitted as OEM in properly (?) designed luminaires. They are worse when dropped into your 'incandescent-designed' Disco headlights.
Also, you get what you pay for. A pair of dealextreme-priced HID's had to be unglued from their bases and laboriously re-aligned when I tried a set in the low beam of a Jap import. - Still not 100%, and will need an internal baffle to reduce the glare....
By the way, is the awesome-ness of your 55W/6000K HID's in relation to how they light up the road ? - is the road surface nice and BRIGHT ? How well do they light up (on low beam) those green freeway signs? - and the road-edge markers.... are they dazzling at 500 metres too?
-Why is that a Good Thing?
Most 35w HID's put out nearly twice the light of a good incandescent, so if you neeeeeeed 55W on low beam, maybe its time you had your eyes checked.... Or get rid of your 'Mafia-Tint' windscreen..... :p:p:p
By the way, dunno what its like over on your side, but over here folk don't flash (its illeagal...) for anything less than half a dozen spotlights burning out their eyeballs. Not like it was 20 or so years ago...
Parting thought, on a country road its easy for oncoming drivers to behave like moths... Paradoxically, the brighter your lights, the more they do and slower to react, are they...
