One of the most difficult things about trying to find an address at night is I'm not a vampire, so I can't read the numbers in the dark. The Solar House Number Display & Mailbox will save you from hours of circling the block until dawn. It collects ye old Sol power throughout the day, and provides up to 10 hours of backlight at night for your house number. It doubles as a mailbox, but if you don't get paper mail anymore you can install a tiny disco ball and all the local hip birds can hang out in it. $128.
