Lots of people don't put up house numbers, which is a pain for delivery drivers. It can even be hard to spot in the clear daytime, no less at night while its raining.So, what I propose is to sell Backlit House Numbers. No explaining really needed... except that they would come in a variety of colors, of course... you could get hot pink for a college girl's dorm, blue for those who want something different, or, plain white for you boring folk.-- ghillie, Oct 15 2004 (??) Solar House Numbers http://www.rusticst...ered-house-sign.htmOne backlit design version. [jurist, Oct 15 2004] They could be solar collective in daylight hours. They also already exist. I couldn't find a picture of them [ghillie] but if you type your idea title into a search engine there are many references.-- 2 fries shy of a happy meal, Oct 15 2004 [jurist]: That wasn't really the kind of backlighting I was going for... I was thinking that each number would glow individually, and would be hooked up to a main unit.-- ghillie, Oct 15 2004 random, halfbakery
