TEXT: For some future projects I ask you to answer the following questions

1) To turn the adjusting screws of a HB2-headlamp it will be necessary to remove two snap on covers without the use of any tool. Will this be legal?

2) A combination of HB2-headlight (low- + high-beam) and auxiliary driving beam in one unit shall be equipped with only vertical adjusting screws for the driving beam. The beampattern will be so wide, that even bulbs with extreme tolerances will allow t o meet all photometric requirements without horizontal adjustment. Will this be legal?

3) When will the 9007 bulb be legal? Date of final rule?

Thanks for a quick answer
