The relationship between your iPhone and transportation is no longer limited to Google Maps. Meet some of the new iPhone applications that will help enhance your ride if you already have your way around town figured out. The BrakeLights application will allow you to turn your iPhone rather literally, into brake lights for your ride. This application will be able to detect when you brake and flash a red light on the screen with an accelerometer. BrakeLights are now available on iTunes for just$1. We don't really suggest strapping your gadget to the back of your bike or moped, but securing it to your bag could be a fun idea to do.
