Plug and play, no modification with factory 7443 bulb size

Multiple brightness levels available

Overview

Instant On and Off. The factory incandescent tail lights and rear turn signals on the Ford F-150 illuminate in a slow glow, taking a moment to turn off and on. A modern LED upgrade provides instant response, which can alert other drivers on the road earlier, while also providing a modern LED appearance. This instant activation adds a modern and distinct look 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.

Tail/Rear Turn Comparison

Correct Color. Since the lens on your tail light housing is red, you'll see that we only offer a red color option, which is correct to SAE/DOT "red" requirements. Red is the correct emitter color for maximum turn signal output on your F-150.

Reduced Load. When it comes to LED upgrades, you'd think the lower power draw would be a great feature! However, the F-150 looks for a specific power draw from the turn signals. LEDs will make the vehicle think a bulb has gone out, due to lower power draw. This causes a "hyperblink," or fast-blinking turn signal, which can be corrected with LED Resistors or an LED Flasher.

The most basic, tried-and-true method to correct hyperblinking is to add resistors. Since a 6-ohm resistor uses about the same power as a standard turn signal bulb, these can be used on any vehicle, but does require tapping factory signals. One resistor is needed to replace each turn signal bulb.

You may have also heard of flasher relays, which is the actual module that determines flash speed. On some vehicles, it can be replaced with one that is designed for LED power levels. However, on many newer vehicles these modules cannot be replaced. If it's possible to replace the flasher on the F-150, you'll see one listed above. Only one flasher is needed per vehicle, for both front and rear LED turn signal conversions.

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 an increasing number of 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!
