i dunno if its real, but there is a guy who got arrested for buying something off ebay that could change lights

he did it every morning at like 530 or something

and eventually they figured out that the light kept malfunctioning as soon as his van arrived..
ok dont not so good something is something ok ok ok gogogo

Idea does seem probable. If you look closely sometimes at certain lights there's a small, black, upright cylinder with what seems like a IR sensor sticking out of it. It could be a camera or numerous other things but the idea doesn't seem too far fetched. However, i doubt it would be possible to make a universal remote that will activate the sensor. There's no way for you to find out what the proper signal is since it doesn't seem to be universalized, and i doubt you'll be able to send a signal far enough to make it practical. If your range on the remote is only 20 feet it'll require you to slow down to like 10 mph unless you wanta risk running a red light and smacking into some unsuspecting motorist .

Don't the emergency vehicles turn all the lights red and just run the red light? I don't think they turn them green if thats even possible, the abuse/hack problem is why. I know near most traffic signals there is a control box and if you have a key you can set the lights to cycle differently, or all hold red, or flash red etc. My tweeker friend's dad was a police chief he had all these keys and wierd shit that cops have to control things. I don't think flashhing light sensors changes lights. This sounds like a job for Adam & Jamie

That video is definitely a hoax. Even if it did work the range on a remote for your tv would never be enough.


PS- I've also heard that if you press the crosswalk button 100 times as fast as you can it will change the light to let you walk. I'm pretty sure that doesn't work.

There's always different things. Some are controlled under the ground, some lights react to the specific light from the police's flashing lights.

That's why you see certain drivers flash their highbeam when the light isn't changing quickly enough.

http://en.wikipedia.org/wiki/Traffic_signal_preemption
http://en.wikipedia.org/wiki/Traffic_lights#Unauthorised_pre-emption

+ Show Spoiler +
There have been some concerns that unauthorized people may have obtained devices that can trigger light preemption. The original 3M Opticom pre-emption system was activated by a 14 Hz strobe light added to the light bar of fire trucks, ambulances, and squad cars. When the sensor senses the 14 Hz strobe signal, the pre-emption is activated. The 14 Hz "secret" was eventually discovered, and MIRTs (Mobile InfraRed Transmitters) hit the market, consisting of a 14 Hz strobe with an infrared filter installed on it to make the light invisible to the naked eye. The use or sale of such devices in an unauthorized context was made illegal in the United States in 2005.

In some jurisdictions, traffic lights are set to turn red in all directions when the pre-emption system is activated, rather than holding one direction green to allow an emergency vehicle to proceed with traffic. This stops all traffic except for emergency vehicles, which are permitted to proceed through a red signal anyway, and thus removes much of the incentive for an unauthorized person to manipulate the pre-emption system to their own benefit.

3M has developed an encrypted Opticom system.[5] However, jurisdictions already using the original system would have to replace the original traffic signal sensors and vehicle-mounted emitters in order to use the encrypted system.

There have been recent concerns about the security of traffic light preemptive systems and the actual underlying network controlling them and traffic lights in general. An article in the hacker E-zine Phrack has outlined flaws in the traffic controlling system that could allow an unauthorized malicious person to abuse it as he sees fit. By issuing valid signal controlling messages from the area traffic control center if access is gained to it, an attacker could essentially control any phase, test phase, preemptive signals, or any function of the traffic system that is controllable remotely. The article also sparked a response by Transport for London where it is reported that a skilled attacker armed with this “step-by-step” guide could in fact cause malicious damage, as reported by a Transport for London spokesman..

This exists, it works, and it's incredibly illegal. You're allowed to have one, but if you're found using it, good luck in life.
