And to add, here in California there is what is known as a "special Contstruction Vehice". There is no original light per say from manufacturer. All you need to do is get them certified, I believe, by DMV. They need to have a beam that is patterned not to shine into oncoming traffic. I am not sure of the particulars, but was just having a conversation about it with a cop friend of mine. We were talking about the legalities of my HID lights.
1st, he told me he has only ever pulled over someone where their lights are so far out of adjustment that they shine into oncoming traffic or just to bright. With LAPD, they are told that the only light violations are "additional" aftermarket lights over a certain amount of inches from the ground, and lights that do not have a directionalized beam (Flood lights). When he looked at my HIDs from a distance he told me he sees worse from BMW's so go figure.
People can rally all they want. We had a local congresswoman pushing for a ban (lost) then a higher tax (still in limbo) on SUVs. She must own a Honda Civic. Then there was the group trying to push a ban on Motorcycle exhaust (again failed, but I can understand it sometimes). There will always be groups that try to push things and luckily we live in a country where our freedoms are not easily yanked away. We will see.
