Overview
Modern Style. Replacement LED bulbs are a simple way to improve the look and styling of the dome lights on your GMC Sierra. Compared to the original incandescent bulbs, they will provide a brighter appearance with modern color. The installation is straightforward, with just a bulb swap - making this a great simple upgrade for the Sierra.
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.
Color Options. In addition to vibrant colors of blue, red, and amber, our dome light bulbs are available in a cool white 6000K, and warm white 3000K. Whether you want a modern cool white appearance, or a traditional warm white color with more output, we have the color to fit your needs!
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 Sierra. 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 GMC 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!
