Howdy all, I have a 2020 GMC Sierra Elevation and came here looking for an answer to this exact question. I apologize in advance for asking this, but what I see from the thread above is the headlights are an LED unit and are not replaceable with something brighter? I can live with the high beams the way they are but would love to have brighter low beam headlights. And just out of curiosity what happens when a light burns out? There must be a replacement unit? And would there not be someone who makes a brighter unit? Thanks a lot and happy motoring
