Solar-powered Keyhole Light

Once in a while, we stumble across something that’s so basic and essential, we tend to kick ourselves in the ‘nads thinking, “Now why didn’t we think of that before?”. After all, a practical invention like the Solar-powered Keyhole Light would certainly be a hit - we don’t see anyone not wanting to own one of these. Since it derives its juice from the sun, you don’t have to fork out more money each month to keep it powered, and it offers a convenient way to enter your key without fumbling whenever you return home to your apartment/house late at night, regardless of whether the street lamps around are working or not. Brilliant.
