Didn't really know where to put this, mods move if you want. Thanks

Here it goes....

When I have my radio turned on and I turn the parking lamps on, just the first mark on the headlight switch, my radio turns to static and I can't hear anything. But if I turn off the parking lamps or headlights, the radio goes back to normal, no static.

Does anyone else have this problem???

I just recently installed a set of Hella Micro DE fog lights, would that have anything to do with it?? Like the ground wire?? Power wire??
