The hazard/turn signal flasher in a 2011 Ford F-150 is a small electrical component that makes your vehicle's lights flash regularly. It's situated beneath the driver's side dash and is connected to the turn signal lever and hazard switch buttons. If you're experiencing problems with your turn signal relay, you'll quickly notice some signs. Your turn signal might blink too fast, stay on without blinking, or not work at all.
The Ford F150 does not have a flasher relay; instead, it is controlled by the BCM (computer). When replacing the bulbs with LEDs, it is necessary to install resistors rated at 2.5 Ohms and 65 Watts.
