We all have a mischievous side hidden away deep in the darkest depths of ourselves, well now is your chance to let a little of it out. Have you ever driven down the highway and seen those large orange electric road signs, they usually come with bad news: bridge closed, accident ahead, road work and even zombies ahead.

That’s right, zombies. Thanks to a post on the sight i-Hack.com, the secret behind the glowing amber lights has been unlocked allowing merry pranksters to meddle with the machine’s messages. Once access has been gained to the interior of the unit, there is a programmable key pad that allows authorized personnel to put up the required text that also means that you too can reprogram it to say whatever you want. Even if the device has been locked, it can be reset by holding a certain sequence of buttons.

So you can have fun, but don’t get caught by the authorities, not sure the department of transportation would be too happy about you messing with their machinery. So follow the link to get the full details and watch out for those zombies.
