With regard to halogan headlights.  I have a set of hella lights with 60/100
bulbs and I prefer the beam pattern of the Hella's.  Instead of having the
low beam project uniformly as normal lights do thus:

     
	  .....			   .....
	.........		 .........
       ...........	        ...........
       ...........	        ...........
	.........	         .........
	  .....	                  ......

They project a beam the looks like this (low beam)
     
	       			        
	         *		           *		The dispersion pattern
            *******	              *******		is significantly wider
     ***************	       ***************		so more of the sides of
      *************	        *************		the road are lit up.
	********	          *********		  (brighter too)

Also, you can see that the pattern is somewhat truncated.  This allows you
to have the beams aimed higher without having it in the oncomming driver's
eyes.  

I believe that the lights robert were referring to (cbi's?) have a truncation
pattern like a ruler, instead.  Also those lights were 90/100 instead of 60/100
which means that they really were brighter.  These bulbs could also be used in
the HELLA's but cost $20 each, instead of $10.  

In any case, ANY lamp that is not sealed beam is likely to be better.
