   good idea? extra (small) "headlights": u

   From: dkcombs@panix.com   
      
   Am just notth of NY-city, dark at 5pm, go to pick up   
   wife at train station; all men are wearing black   
   or dark brown coats and pants, it seems, and are   
   plain INVISIBLE when crossing the street or walking   
   along it.   
      
   Unless the headlights are pointing right at them (on   
   high), you can't see these people, as many of them   
   walk home from the commuter train.   
      
   These people, when still near the station, are all   
   over the place, going every which direction,   
   AND YOU CANNOT SEE THEM.  (Nor could you.)   
      
   (I'm sure you know what I'm talking about!)   
      
   So I was wondering -- ultraviolet light makes at   
   least some clothes emit light, light you can SEE.   
      
   (1) would dark clothes, coats, shoes, and hats,   
       and even skin, suddenly become more visible   
       under ultraviolet light?   
      
   (2) Would it hurt anyone's eyes to look right   
       into it?   
      
   (3) Can you buy any that would run off a 12 volt automobile   
       electrical system?   
      
      
   I guess you'd mount one on each side of the hood,   
   pointing 30 or 40 degrees to the side.   
      
      
   So, what do you think of this idea?   
      
      
   (Hey, if not ultraviolet, how about gamma rays? :-)  )   
      
      
   Thanks!
