I have noticed that every time i turn on my HIDs it creates static when im listening to the radio. Did i connect the HIDs wrong? Or is there something i can do to stop this from happening. I got the HIDs from HDNation. Any help would be helpful

This happens sometimes. Some aftermarket kits are noisy. You can rule out wiring my connecting them straight to the battery and see if you still get the same problem.

I just installed LED fog lights and they cause radio interference as well... god damnit!

LED lights should never cause any radio interference - they don't generate RFI. HIDs are different because of the ballast and high voltage. I would be willing to bet that you have alternator or ignition noise in your system unrelated to the LED fog lights.

LED lights with any decent efficiency will have a switching
regulator in them, operating in the hundreds of kHz to low
MHz range.

You might want to play with grounding and decoupling,
add some cceramic caps close-in to wherever the lamp
control electronics reside (like a few 1uF 50V, and maybe
10-100uF 50V electrolytic or tantalum while you're at it).
An inline common mode choke or canned EMI filter could
be even more effective. These can often be scrounged
from industrial computer / control equipment and are cheap
iin any case.

The LEDs I bought for the fogs aren't just replacement bulbs, they came with a little black box that looks sort of like what comes with an HID kit (not the ballast but the other box). I'm guessing that's what is causing the interference. The radio reception only sucks when the fog lights are on; you can have a station playing with great reception, then you flip the fogs on and reception goes to shit. It certainly didn't do this with the stock fog bulbs.
