I definitely following this.I have HID capsules in the OEM reflectors, and the beam is so unfocused that the local constabulary wants to discuss my beam pattern with me every time they see it.
Typically, they object to it in a way that makes it quite clear that they want me to change it...as in NOW.
I have 55 watt HIDs which are pretty bright.
Mine are 5k, which is very white w/o being bluish.
Yellower is actually better in foul weather...but the light from the bluer lights is almost invisible on wet pavement, etc....and are worthless if foggy, etc....so for me ~ 5k is the Kº ceiling.
The OEM lamps suck, so I do want to upgrade to something potentially legal.
