Heritage Auction is hawking 5 light bulbs and a socket preserved from the 19th century. Edison Electric used the gear during lawsuits against companies he claimed were copying his bright ideas. Heritage's estimate for the lot is $10,000 ... but expect to spend much more than that conservative number if you're interested.
Not into dead light bulbs? There's also a set of keys to Edison's Menlo Park lab where he invented his first commercial light bulb. Asking price -- $6,000!
You can bid online or in person in Dallas, starting December 3.
