At night on the Singapore River you can ride the Bumboats where you cruise down the river and around Marina Bay.  At one bridge over the Singapore River they have a lot of blue lights that illuminate the river.  I captured this photo near that bridge at Clark Quay.

I love the wobbly blue reflection – such a deep blue, almost purple, against the black color of the river at night.  The 3 while lights from short reflected in the wavy river adds an interesting element.
