    Replaced all lights with led's and changed flasher to one for led's the one with ground wire. The problem I'm having is it keeps going through the flasher. I've replaced it 5 times already any suggestions on why this is happening?

    Do you have condensers on the wires to the bulbs?

    I replaced all lights with Leds , but what I had to do was leave 2 of them (regular lights), which were the turn signals on the pods on the 379 model and all worked well . I was using the original flasher. I was told the flasher needed to be excited to work properly, anyhow this is what worked for me

    Make sure the led flasher you got is rated for the correct amperage. There are ones that are only ment for a pick up, that can't handle the load if your trailer isn't all led
