Traffic In The Cold

Well.. here it is ... a picture not featuring the cat!

I thought I'd put a little effort in tonight and venture out in the cold for this.

I'm really trying to get used to the correct settings on Manual - I've done light trails in Shutter Priority which I think were clearer than this one.

If you have done light trails before, which lens did you find the best? And, any improvement tips are welcome :-)
