Make sure the pizza delivery dude never misses your house again with these Solar LED Address Numbers ($20 each). Powered by sunlight, each number has two white LEDs hidden behind the number plate, which sits an inch from the mounting surface to create a great backlighting effect. Plus, there aren't any wiring or timers required for installation, since the lights come on automatically — giving you one less thing to worry about.
There is nothing that we miss more living in an apartment than having a friendly door bell for folks to ring, as opposed to the coarse rapping of the knocker. If you feel the same way, consider alleviating the problem with this wireless Jacob Jensen Door Chime ($145). It features a clean, modern design and five polyphonic chimes to announce your guests' arrival in style.
