Depending on your vehicle of choice and experience behind the wheel, backing up can be one hell of a dastardly task what with the kids, other cars, people and more objects to contend with. One possible solution to this is products like the "Our Lady of the Trunk." This device is a backup alarm that connects to the brake lights. Put your vehicle in reverse and a deafening 100dB female voice will warn all around that you are backing up. It's available for $10, which makes it a pretty much a no-brainer for those without dignity, class or Murilee's ability to fashion creative solutions out of junkyard parts. We're still checking if the alarm could be modified to work with forward-moving vehicles. [American Science & Surplus via Giz]
