SS3 SAE GMC Sierra 2003 Fog Light Kit

The Diode Dynamics SS3 SAE GMC Sierra Fog Light Kit is a direct-replacement LED fog light upgrade built to give your Sierra noticeably better forward visibility in low-visibility conditions. Using TIR optics and high-intensity automotive LEDs, this kit delivers a clean, factory-style appearance that looks like it belongs — not like an afterthought.

Choose from Sport, Pro, or Max output levels depending on how much brightness your driving demands, and select either White or Yellow SAE Fog beam pattern to suit your preference and conditions. Yellow is a popular choice for heavy rain, snow, or dust, while white provides crisp, natural light for general fog and night driving. Both beam patterns are SAE-compliant for road-legal use.

Installation is straightforward thanks to vehicle-specific mounting brackets designed to fit your Sierra precisely, no drilling or fabrication required. Whether you're hauling on dark rural roads or navigating a worksite at night, this kit is a practical, no-compromise upgrade over your factory fog lights.
