Twin Green Online and eBay are two of the most convenient places to search for and purchase used traffic signals and other refurbished municipal equipment. These sites allow buyers to search through listings of used traffic signals with keywords and catalog searches.
Twin Green Online refurbishes and collects old and used traffic signals, municipal signage and other urban development waste. They offer it for sale to private buyers for use as decorations or on private property.
eBay also boasts a large, constantly shifting catalog of used traffic signals. Items are offered at auction, and buyers can bid on lots or sometimes offer direct purchase for a consideration.
