AUTOONE Upgraded LED Side Marker Lights 2PCS

This LED side marker kit upgrades the factory fender lights on large GM SUVs, bringing brighter white illumination to improve side visibility when changing lanes or parking. Designed as a direct plug-and-play replacement, the set fits the 2021-2024 Yukon, Yukon Denali, Yukon XL, Tahoe, Escalade, Suburban, and Escalade ESV and aims to eliminate flicker and error codes while driving in varied conditions. ⚡

Key Points

The kit includes two smoked lens driver and fender side markers that plug into the existing sockets without modifications. According to the manufacturer, the double‑row LED layout and higher-power chips deliver substantially greater brightness than standard bulbs, which helps other road users notice your vehicle sooner. The housing is made from ABS plastic with a polycarbonate lens for impact resistance and clearer light output. Note that these are white LEDs with a smoked lens, so the visual effect differs from clear-lens white markers.

Advantages

These markers are engineered to resist water, dust, and shocks, which supports longer service life when exposed to rain, snow, or off-road conditions. Installation is straightforward and designed to avoid common LED swap issues like hyper-flashing or radio interference. The smoked lens offers a subtler look while retaining strong white light output, giving a blend of style and function for owners who prefer a less obtrusive appearance.

Usage Recommendations

For best results, disconnect the vehicle battery or follow the vehicle manufacturer’s wiring precautions before swapping the bulbs to avoid any electrical issues. Remove the existing side marker by unplugging the original connector and insert the AUTOONE unit until it seats firmly. Test the lights after installation to confirm there are no error messages and that the markers illuminate consistently. Consider that color perception through the smoked lens is different than clear lenses, and verify local regulations regarding marker color and brightness if necessary.
