Well that's tasteful and unostentatious, and there is no danger that airplanes accidently try to land in your driveway. :)
In Germany it is not common to do that, btw. People may put a little christmas tree with lights in the windows, or other christmas symbols with lights. But not lights all over the house, or even those dangling Santas or reindeer on the lawn and such.
Well, I guess it will be a strange christmas this year. But all the best to you and your family anyway!
