Re: driving/pencil/fog

Fog:  short range (low beam) wide angle horizontal, sharp cut vertical.....
 Used for low visibility conditions, rain/fog/dust/snow

Driving:  long range (hi beam) narrow angle horizontal  narrow angle
vertical......  Used to augment hi beam stock lighting

Pencil Beam:  very long range (hi beam) extreme narrow horizontal extreme
narrow vertical usually used in conjunction with Driving lites, considered a
very "hot" highly reflective beam pattern with a very small "pencil of lite"
at long range

Euro H1/H4:  Considered the same as a fog at low beam and a driving at hi
beam....  Sharp vertical cutoff at low beam with wide horizontal angle
