With aggressive drivers that enjoy tailgating other vehicles in mind, a hacker decided to built a method to communicate to those annoying drivers without using obscene hand gestures.

Hacker Gagandeep Singh has developed a do-it-yourself project for designing a grid of LED lights on the rear window of a vehicle without obstructing the view from the rear-view mirror. Singh is interested in providing feedback to drivers that don’t pay attention to the rules of the road. Using his Volkswagon Polo as the guinea pig for the project, Singh created plans for a 40 x 16 LED matrix display with LED lights that allowed two centimeters of space in between each LED in order to still see out the rear window. He then used a strip of wood to accurately measure out the distance between the LED lights and spent the next two days soldering the lights into the full matrix display.

LED-display-within-carAfter attaching all the wiring at the bottom of the display and making sure the matrix lit up, Singh attached the matrix to the interior of the Polo and connected it up to a AT89C51 micro-controller. This controller allows Singh to design patterns as well as messages and watch them display in the rear window. For instance, Singh could ask a tailgating driver to back off his bumper while traveling down the highway. While entering messages into the controller is likely too much of a distraction while driving the automobile, the next stage in the project will enable updating the matrix through a Bluetooth connection on a mobile smartphone. 

While others can follow Singh’s instructions in his Google slideshow detailing the entire process, it’s unlikely that this matrix would be adapted for the mass market. Abuses of the technology could easily lead to distracted drivers on the road as well as angry drivers if the matrix was used to display obscenities. In addition, any object that blocks the rear window at all would likely be frowned upon by lawmakers.

  1. Dano Jahnke at 5:04pm 24th October 2011 think of the possibilities....
  2. Kimberly Swartz George at 12:07am 23rd October 2011 LOVE IT!!!
  3. Tyler Roden at 9:34pm 22nd October 2011 Lol, how many people looked at this and said I thought of that years ago!
    1. Aaron Timm at 10:43pm 22nd October 2011 I actually thought more of using one of those LED displays like are in the stores. Then you just preload it with things, doesn't block the rear window, already comes with the necessary programming. I just hardly ever drive a car and there isn't room on the back of a bike for anything of meaning.
    2. Russell Tavares at 2:59am 24th October 2011 I certainly did, I wanted the cafeteria red and green scrolling one, to warn of tailgating, "hey grandma, your blinker is on", or "convoy make the next left", "your high beams are on", or even "if you pull me over officer, I'm recording you."
  4. Dave Moehle at 9:21pm 22nd October 2011 Me too Justin!
  5. Stephen Meese at 9:19pm 22nd October 2011 This doesn't classify the person as a hacker. This is just some guy/girl who programmed this set of lights, based off other peoples' work, and put it to use in their car.
  6. Justin Belshe at 8:33pm 22nd October 2011 I've wanted one since the 1980s!!!
    1. Gr8Music at 6:23am 24th October 2011 I've wanted one for years myself - except for the front of my car, in mirror image. These days it would permanently display "Get OFF the phone and DRIVE" with the occasional "Those Shiny Things are used to see whats behind YOU - Move Over!"
  7. John Wade at 8:23pm 22nd October 2011 A roof mounted remote controlled M240B would be more useful, it could also serve as protection or clear traffic
  8. Chris Johnson at 8:20pm 22nd October 2011 Yeah, it will be great the first time someone fires on the "Don't tailgate me, bro" and the offender leaps out of the car at the next light and proceeds to shoot Captain LED.
    1. Russell Tavares at 2:57am 24th October 2011 Yeah, clearly all those crazy people willing to break the law and tailgate are psycho killers waiting to happen. And if a guy has a giant hacked-together LED string, what are the odds his vehicle isn't already recording whatever goes on around it? (Heck, at a traffic light, there are ALREADY cameras watching, we all know this.)
    2. jesterking at 7:29am 24th October 2011 Which is why I carry my .45 everywhere. Why don't you?
  9. Bristol Eastwood at 8:18pm 22nd October 2011 Parabolic mirrors that spring out would be great against the drivers that use their highbeams the entire way, blind them back :)
    1. easy victor at 8:17pm 24th October 2011 I actually do this already w/ the vanity mirror on the passenger side. It works quite well!
