You are on the right track.  Finding just the right time to get the
effect of the lights themselves and the object they are on is a little bit
of a trick.  Since you crossposted to both digital and traditional ngs I
can't offer much advice as the tricks are different for the different
equipment.

    I suggest you also consider rain as well as snow.  It does not need to
be raining, but the reflections can be a great effect.
