When i am indicating, and then apply brakes the brake lights flash and dim. I have tested all fuses in box next to car battery and they are good. Next i removed both rear light clusters, passenger side cluster had a little rust so i cleaned it.

Driver side cluster the terminal from car the metal strip that is for wire 3 looks like it has been pushed into plastic housing. I tried bending back into shape with pin no luck.

I then re-attached passenger rear light cluster, and tested indicator and break and it still flickers.

Really stuck with what to do next.
