 Hi, 
  
 Has anyone used these portable traffic lights?  This looks like something 
 that could save a few flag worker lives.  Instead of standing in the road, 
 put 
 one of these portable traffic lights out there and control it from the 
 corner 
 or better yet, from inside your car. 
  
 They also seem to do custom traffic directional lighting.
