   Some xenon headlights, yes.  But LED brakelights are not too bright.  They're   
   just too flickery.  They appear the same brightness as a standard 21W   
   brakelight bulb to me.   
      
   So why can't this pretend brightness be applied to domestic lighting?  An LED   
   lamp which currently equates to a 50W incandescent could give out what looks   
   like 100W.  If it's not done because people are more likely to notice the   
   flicker at home, then why    
   not have a higher pulse frequency?   
      
   --   
   If it's zero degrees outside today and it's supposed to be twice as cold   
   tomorrow, how cold is it going to be?
