16-18 Sierra Dimming LED Override Harness

 This is only for OEM headlights not aftermarket headlights.

This harness is for those with 2016-2018 GMC half ton Sierra SLT's and Denali's that use the below pictured headlight.  This harness will keep the LED bright at night instead of going dim. This harness simply plugs inline with each headlight, no added fuses or tapping is required. This harness will not work on the non SLT headlight.
