Just found this... One of many storys I have found on LED bulbs in GM Trucks..
on my 2005 chevy avalance i install led bulbs on the front turnsignals now my blinkers blink crazy fast i read that i can buy a electrnoic turnsignal blinker fix relay but i dont know where this is located can does anyone know where this goes?
Most of the time you can add resitors to stop this..
