Does anybody know why one turn signal on the front would be brighter than the other? I’ve used multiple lights, ran new wires and sockets, swapped bulbs around and same problem. It did this with the stock equipment as well. The right side is always slightly dimmer. Any help appreciated

 

Probably has a crack, and water has got inside it, and the shiny reflective surface in there is all corroded.

Easy enough to check; take off one of the lights and carry it over to the other side, and stick the other side's bulb in it. If the left bulb is dim inside the right housing, or the right one is bright in the left hsg, then it's gotta be the housing.

 

I thought it might be that as well but when both bulbs are out of the housing it still does it
