Radio interference when using ditch or fog lights with Aux switches

[‘21OBX]

I’m not finding it in a search so.

anyone else radio go straight to static when running the ditch lights?

I grounded them right to the cowl panel with a factory ground is that the issue?

This happened to me when I had the Stubby antenna installed. Put stock back on and doesn't happen anymore.

We have the stock antenna. I have to wait until I get mine back from the dealer but I don’t think mine has the interference. Same lights only difference is I don’t have Aux switches so mine are fed off the rear fog light switch.

Oddly enough it happens with the fog lights too activated buy the Aux switch.

I have 6in pod lights on the cowl and don’t have any issues with static

Sounds like a grounding issue with not enough AWG for the resistance. what AWG is your ground wire and is it sharing the same ground as another piece of equipment that is consistently "on"

Cheap chinesium unshielded LED lights are notorious for this, along with backup camera static. What brand of lights?

Mine are niighlight from Amazon. Mine did the same, I switched my stubby back to the old whip and seems to be fine. I stream music mostly so I sswitched back.

I run diodes for ditch. They do it with the trek antenna. Stock antenna is fine.

Where did you ground them? Although mine are grounded to the same spot on both vehicles. Maybe I just missed it on mine. The ditch lights will probably never be a problem. But the Amber fogs may get used on road.

oh they definitely cheap lol!
the ditch are $23 on Amazon, the mod bumper setup I do not know the brand I got them at a Bronco meet with brackets and everything.

ground for fogs are 12 Guage as that’s what I had on hand.
ditch lights are 16 Ga. Grounded here.

I used the grounding point by the driver side cowl for both lights

I’m going to be installing some ambient lighting on another Aux switch soon. I’ll see if that has the same effect

Electromagnetic interference is likely the culprit. Try getting some ferrite clamps for the wires.

Clamp one around each set of positive and negative wires.
