In the Q days, the Gyra-lites or "Mars" lights had a figure 8 pattern. 
Later versions had a circular pattern, but those were after the BN was 
formed. Gyra-lites, while very effective, fell into disfavor over time 
due to high maintenance costs. Flashing or beacon lights were less 
complicated and cheaper. The Gyra-lite mechanism was actually a gear 
drive platform designed to move the light in a particular circular or 
figure 8 pattern. On some RRs, there were reports of the light causing 
a hypnotic effect on the crew. One point of clarification: the 
Gyra-lite was an additional light on the front of the locomotive, not 
the only light. The locomotive still had a fixed beam headlight on at 
the same time that the Gyra-lite was operating.
