fog lights not working

[2018_ram]

I have a 2018 ram 3500 and i put HID fog lights in and fogs don't turn on when my truck is running but they work with the engine off. so I tried searching it but i can't find anything to fix the issue. so I'm hoping somebody on here can help me out.

Same thing happened with my '15 when I put LEDs in the fogs. I eventually had to upgrade to Diode Dynamics CANbus anti-flicker modules and everything has worked fine since.

They are supposed to be good for 35 watt HIDs too. I know some places offer relay harnesses for HID systems.
