Diode Dynamics is excited to introduce our new plug-and-play HP24 Switchback Turn Signal LEDs for the Ford F-150!Switchback. These aren't your average turn signal bulbs - they're Switchback! On your Ford F-150, they will illuminate in a bright 6000K cool white color as the parking light, 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.



Fitment. These bulbs are a direct replacement for your Ford F-150’s front signal bulb. Installation only takes minutes - simply take out your factory bulb and the HP24 will fit snugly in the socket. However, we do recommend LED Resistors to prevent bulb-out warnings and hyperblinking. See how to install resistors below.

NEW! Since some Ford trucks use a 4257-size front turn signal bulb, we recently released a 4257 HP24 Switchback bulb. The 4257 HP24 Switchback bulb features a custom-molded base connector, making it a true replacement for factory incandescent 4257-size front turn signal bulbs. Unlike a 3157 bulb that includes tabs on either side of the bulb, a 4257 bulb does not.Brightness. At 410 lumens, the HP24 will provide about double the total light output compared to your factory bulb. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. We test the true output in-house and provide you the real numbers to compare.Colors that match. Most of us have seen lighting setups with random shades of white that don't quite match. At Diode Dynamics, we operate an integrating sphere, which is a piece of lab equipment used to analyze the exact color spectrum of the LED bulbs we produce. By testing each batch of products, we can ensure that all bulbs will match in color, to avoid various tints of white. These bulbs will match any other upgrades you may have from Diode Dynamics, for factory-style uniformity and a clean appearance.Reliability. Diode Dynamics LEDs are built with constant-current inductive circuitry, along with transient suppression. They are tested by our 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. This is what kills most LED bulbs over time, but just like factory components, Diode Dynamics LEDs are designed with built-in circuit protection. While more expensive than simple bulbs, this allows Diode Dynamics LEDs to last for years, with no flickering or failure.
