Default High Beam indicator always on

So I have a 2003 mustang v6 base model, installed aftermarket cluster with with LEDs, it was working fine, but this morning when I left for work, I turned on my headlights and the high beam indicator turned on, even when I didn’t set the indicator, now the indicator is always on when I turn on my lights, turns off when I just turn on my daytime running lights, but when I switch from my low beam to high beam function and vice versa, the indicator stays on and also the lights aren’t cycling back and forth, the light stays the same, and I’m not even sure if it’s my high or low beams that are staying on. And idea what this could be?
