That's bad.

I have an aftermarket HID kit in my car. It has been tested and properly aligned by my Honda dealer. And nobody has flashed their lights at me so far, in over 10.000 km of use.

Because I knew what I did and why, and made sure it worked.

First of all, my car has projector lenses. I bet they use the same lenses whether you get them with OEM HIDs or not. I had halogens and they produced very little stray light, to the extent that other road users seemed to overlook me at night. One lady almost slammed her car into me, driving along a long line of slow moving traffic and apparently my car was the 'hole' in the line!

I chose the color carefully; 5000K which appears plain white.
When I got the HID kit I carefully measured the position of the electrodes (they were at the exact same position as the middle part of the filament of my halogens) and when I fitted them I made sure they were positioned right, though my Honda dealer readjusted thenm all the same afterwards.

I am very happy with my HID kit and although I see a lot of badly aligned HIDs around, I am pretty certain that mine is not among them.
