Strange light pulses infront of a garage at dusk

I generally love to have a stroll at dusk. The place where this photograph is taken is Gachibowli, Hyderabad, India. I had casually taken a pic of the surrounding and it was around 6:30 pm. I didnt see any of these light pulses while taking the pic with my Samsung Corby 2.0 megapixel mobile camera. However, after the pic was captured, I noticed these strange light pulses. Sometimes mobile light-emitting objects like a moving car with headlights turned on, can produce such effects. However as you can see there were no cars moving around the place while I took the photograph. And in the backdrop, its a garage or maybe some shop, I am not sure.
