LASFIT 921 LED Reverse Light Bulbs for GMC Sierra 2014-2026 HD — 6000K Cool White, CANBUS Ready, 2-Pack

Overview

Upgrade your GMC Sierra’s rear visibility with LASFIT 921 LED reverse light bulbs. Designed for 2014 through 2026 Sierra 1500, 2500, and 3500 HD models, these bulbs deliver a bright, 6000K cool white light that helps you see the ground more clearly while backing up, especially in dark or adverse weather conditions. The system uses high-performance 3030 SMD LED chips to maximize illumination while keeping a clean, modern look that suits the truck’s styling.

Built with an all‑aluminum body and an intelligent IC driver, the LASFIT 921 aims to stay cool under use, reducing heat buildup and helping to prolong the bulb’s life. The result is a reliable upgrade that contributes to safer reversing without altering your vehicle’s electrical setup. The design prioritizes a true plug‑and‑play installation, so you can upgrade without chasing extra parts or complicated wiring.

Key advantages

• Bright, high-contrast light that helps you spot obstacles and curb edges more easily when backing up in low light.
• 6000K cool white tone for a modern appearance and improved night visibility.
• CANBUS ready to minimize flicker and avoid common error codes on compatible Sierra trims.
• Aluminum construction with intelligent cooling for dependable performance and extended lifespan.

What you get and how it helps

• 2x LASFIT 921 LED reverse light bulbs designed to replace stock 912/W16W style units.
• Direct 1:1 halogen replacement, non‑polar and plug‑and‑play for quick, tool‑free installation.

Fitment, durability, and caveats

These bulbs are intended for 2014–2026 GMC Sierra 1500, 2500, and 3500 HD trucks. Note: if you own 2022–2026 Sierra SLT/AT4/AT4X/Denali/Denali Ultimate trims, this 921 bulb may not fit due to the stock housing already using LEDs. The bulbs feature an all‑weather, waterproof build and heat‑resistant engineering to withstand routine driving conditions and temperature swings.

Installation tips

• Plug in the bulb exactly as you would a halogen replacement; if it doesn’t light, remove and reinsert after flipping the bulb.
• No separate resistors or decoders are typically needed on CANBUS‑equipped Sierra models—simply plug and drive.
