Switchback Turn Signal LEDs for Ford F-150 2019-2022
Switchback. 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.
Brightness. 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 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.
Experience. After over a decade in business, Diode Dynamics is one of the most trusted names in automotive LED lighting. We directly assemble and engineer our own products in the United States, allowing for higher quality and performance, with the newest and brightest LED technology. Whether it's a Ford or anything else, we pride ourselves in offering only the best possible LED solutions. Please contact us if you'd like to discuss your lighting project!

Diode Dynamics started back in 2006 by Paul McCain. It started as a hobby. And using some parts from Radioshack, he was able to create some LED accent lighting which he sold to some of his friends.
From then on, the company kept on growing to offer more products and employ more people as they progressed. Today, the company is recognized as one of the most reputable LED light manufacturers in the market offering replacement LEDs, Full LED assemblies, multicolor accents and special unique modules.
From Importers to ManufacturersDuring its early days, Diode Dynamics was just rebranding LED lights from overseas, but as they realize, they could create something better. So from then on, they manufacture their own products and have moved into a bigger facility with their design engineer. The company has its own light tunnel to measure beam patterns and various testbeds that ensures that their product is durable to handle whatever weather condition it is subjected to.
Driven by their passion, Diode Dynamics has become the largest specialty application aftermarket lighting manufacturer in the US.
