Features

• Dual AlphaRex LUXX LED chips produce both a brilliant 6500K white output and a warm 3000K yellow output from the same housing
• Exclusive DoubleTap switchback feature lets the driver toggle between white and yellow output by turning the fog lights off and on within 5 seconds
• Projector lens design focuses light output for maximum visibility and an expansive light pattern
• Significant upgrade over dim, single-color factory halogen fog lights, especially in challenging weather and off-road conditions

Product Description

The AlphaRex 210021 is a pair of DoubleTap dual-color LED projector fog lights built specifically for the 5th Gen GMC Sierra 1500, replacing the factory fog lights on AT4, Denali, SLT, Pro, SLE, and Elevation trims. Rather than forcing a choice between white and yellow fog light output, each light uses dual AlphaRex LUXX LED chips to produce both - a bright 6500K white for maximum illumination and a warmer 3000K yellow tuned to cut through fog, heavy rain, and dust.

The standout feature is DoubleTap: switching between white and yellow output is as simple as turning the fog lights off and back on within 5 seconds, no extra switches or wiring required. Projector lenses focus that output into a clean, expansive light pattern, giving a noticeable visibility improvement over the dim, single-color halogen fog lights these trucks ship with from the factory.

This is a direct upgrade for Sierra 1500 owners who already have factory fog lights installed and want genuinely better visibility with the flexibility to choose the right color output for the conditions, whether that's a clear night or thick fog. AT4X owners should note this isn't compatible with their trim's different bumper design, and buyers without existing fog light provisions on their trim will need additional bezels to complete the install.
