Great sign for N scale
Miller had a great idea adapting their HO window signs to rooftop billboards for N scale. They actually fit N scale rooftops, unlike many of their N/HO signs, which generally speaking are too large. Unfortunately, you don't have all the animations to choose from, this sign give you the choice of either on all the time or flashing, but then that's not so bad considering out of the 46 or so options on the big signs usually only 3 or 4 were appropriate for that particular sign.
Also, if you should ever need them, Miller's customer service is outstanding.
