i so much love light trails.
i did it once in my room and i really jumped out of amusement.
the thing there is to lower the shutter speed at the same time stabilize the camera (or use tripod)to prevent shaky shots, then do bracketing for the aperture to produce a really good result with vibrant lights.
the photo above is taken from an ordinary setting. the trail lights made the extraordinary out of it.
