A pity you didn't see it only while driving past it at speed.
One could include Einstein in the explanation otherwise (you know, 
about that Doppler effect like when a fast car approaches you and 
goes past you with an 'eeeeeeeeeoooooonngg' sound....;-))
While approaching the pitch is higher, due to compressed frequencies, 
after it passes you the pitch is lower, due to stretched frequencies. 
The same could happen with light....just watch the bulb go infrared 
after you passed it....;-))
