Lights causing Radio interference
So I'm having a problem that has been happening intermittently and has recently gotten worse.

I have window pillar mounted Rigid Industries D2 LED lights. On occasion, in the past, specifically when its raining or otherwise damp out (heavy fog etc), when i turn them on, my radio (FM) gets a fuzz/ static. It doesn't go COMPLETELY static, just intermittent signal.

the stock antenna was being held to the side of the light with a bracket. Last week i ordered an Antennax shorty, hoping that removing a physical connection from the antenna to the light would eliminate the static. Well now its worse.

I get no other symptoms of bad ground on any other aspect of the jeep. CD, HDD all fine, no flickering lights or anything.

I'm totally stumped. any thoughts?

I have this problem, I had the rigid d2s mounted on the windshield pillars and it messed with the radio when I turned them on, recently I got HiD lights installed now my radio is even worse, all the time now :(

Mine do the same. I assumed it was because the lights aren't shielded very well and they're right beside the antenna. Not a big deal as far as I'm concerned.

I wouldn't say this is normal. The TJ has the antenna in the same area, and I ran windshield lights with no issue. Could it be related back to the CANbus system again?

How are the windshield lights run, directly to battery or sPod or hacked into the factory wiring?

I'm curious if this also happens to non-LED lights too in the same mounting area.

Could also be the ground to the antenna is not good, or for that matter, the wire itself is low quality. I'd try tapping a ground to the antenna, wrapping the stock antenna wire, and just messing around in that area first.

If you REALLY want to find a workaround for interference from LEDs, read this... RFI Problems

this may be worth a try Ferrite Core 1/4 Cord Noise Suppressor: Car Electronics

just stumbled onto the thread here. I had a neighbor say I should put a diode in line of the lights? I am not an electronics guy so not sure who this would help.... Any thoughts. This is not that big of an issue for me, rather annoying at best-but one that I'd like to try and resolve.
