RedLight GreenLight|工具線上App不用買

This app is an April Fool's joke. It doesn't actually do anything. You can still use it to fool your friends, though.

Many traffic lights all over the US are equipped with a system to let emergency vehicles override the normal light sequence. You may have heard that you can trigger these lights by flashing your brights, but that doesn't really work. The frequency that the light sensor is sensitive to is far too fast to trigger manually.

Enter RedLight GreenLight.

Show off to your friends. Amaze yourself. Make your red light waits a lot more enjoyable.

Here's how it works:

Just press the "Flash it!" button on the bottom of the screen, then turn your phone screen towards the traffic light. The program counts down for 3 seconds, then begins to flash a code. Not all sensors work the same way and RedLight GreenLight may not be effective in all situations.

Use at your own risk. Do not use where prohibited by law. For novelty purposes only.
