I just recently purchased a new 2020 Chevy Silverado 1500 Texas Edition. The truck came with the standard halogen brake lights. I purchased some new LED OEM taillights and thought it would be plug and play but quickly realized that’s not the case. The lights will illuminate but when I turn on the signal it flashes normal for about five seconds and then starts flashing rapidly. The dash screen also reads that there is an issue with turn signal. How can this be fixed? Thanks!!
