Yes, there is a lot of glare on that shot.  It was taken in the 1985-1986 timeframe, with an old 110 camera.  Not my best shot, but I never saw that rig again, either.  Hondok is correct, that is a Federal Twinsonic, mounted low to clear the station doorway.

 

Thanks. Funny how the brain works, with that bit of info I can clearly see it is a twin sonic but until you said that it looked like a white box and I never would have guessed it was a light bar.
