Fits: 2015 thru 2024 GMC Sierra 2500HD/3500HD LML/L5P Duramax Diesel
Illuminate your GMC Sierra 2500 with upgraded Diode Dynamics Backup LEDs. This simple bulb swap will not only enhance the aesthetic of your reverse light, but also provide improved visibility at night. Diodes precision-tested lumen ratings ensure accurate and superior brightness, providing a luxurious and stylish touch to your vehicle's lighting. 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 2500. 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.
