Address the problem of hard to see home designation with these backlit Solar LED Address Numbers. With no wiring or timers, these weather resistant numbers illuminate for 8-10 hours at night, depending upon the sunlight energy harnessed during the day, with two bright LED bulbs per number. My personal problem is I live at a address with a 1/2 designation and they do not sell fractions. Drats. $19.99 per number from ThinkGeek.com.
