The hazard/turn signal flasher is a small, electrical device that causes the lights on Your vehicle to flash in a rhythmic, steady fashion. In the 2011 Ford F-150 it is located under the driver's side of the dash and is wired in-line with the turn signal lever and hazard switch buttons.If You are having issues with Your turn signal relay, You will be able to notice right away. There are a few signs that will alert You about this problem. You will notice that Your turn signal will either blink rapidly, go on without blinking, or it will do nothing at all.

The ford f150 is without a flasher relay. Its controlled bcm (computer). If you are replacing the bulbs with leds you will need to install 2.5 Ohm, 65w resistors.
