At the beginning of the year I put on two LED fog lights, red and black leads to both. switch that came with the lights were a 3 terminal simple on off (just not weather proof). 1 terminal red, 1 black, 1 blue. I just replaced the switch for a waterproof switch. the switch has 4 terminals, 2 each side. I wired the black and red leads and I see power coming on as a circuit on the lit fuse in the on position. but lights not coming on. I have no idea which part to put the blue wire on. Not sure if I need the blue wire on the switch. As far as I know the blue wire powered the light on the switch itself, but that won’t come on, on this switch either. I can give pictures of the switch, wiring and whatever else as needed for the help.
