These aren't your average turn signal bulbs- they're Switchback! On the Ford F-150, they will illuminate in a bright white color, then switch to intense amber when the turn signals are activated. The result is a modern dual-color effect! This is one of the best ways to easily add styling to the F-150.

These vibrant LED bulbs are a direct replacement 
Diode Dynamics LEDs are built with constant-current inductive circuitry, along with transient suppression. They are tested by Diode's engineering team with a device that replicates years of voltage spikes, like the ones generated each time the alternator starts and stops on your F-150.

Please Note: Please check factory socket and bulb size before ordering as some models may use different size bulbs.
