  Yeah , the signature SP light package in the 50's was the stock twin sealed 
beam fixed lights with a double white gyra light above that and then a single 
red warning light on top. I've seen the insides of the gyra lights, it's been a 
long time but IIRC the lights were mounted in a swiveling frame activated by a 
motor and crank sorta like a windshield wiper motor. 
  Fond memories of watching SP freights climb Tehachapi at night with the gyra 
lights dancing on the hillsides as the train twisted thru the curves. 
  For some reason near the end SP started removing the gyra lights and just 
left the bare light brackets in many cases. I guess the newer ditch lights were 
less trouble to maintain but they didn't have the same visibility or impact of 
the gyra lights....DaveBranum
