The messaging is clear, from 1am to 5am daily, the lights that grace this walkway will be switched off; this is part of a green initiative by the Land Transport Authority.
One of the things that make Singapore Singapore, especially if you come from the 'third world' is the sheer number of lights, how well the roads and walkways are illuminated. To me, and probably to many, a well illuminated street/walkway feels safer than a dark one.
Any decision made will have pros and cons. Is there an increase in the probability of crime (low crime doesn't mean no crime!) if lights in streets/walkways are switched off, especially irrespective of weather conditions (stormy nights can get very dark)
Isn't switching to greener source of power for the lights better than simply switching the lights off?
How much of an increase in the risk of crime a price worth paying for being a nicer shade of green?
