2001 ford focus has electronic siren type radio noise on AM 880, not other stations, with the brake or directionals on. The headlights do not seem to cause this effect, the brake lights are stock filament bulbs not LEDs, this is very odd and not so obvious, what do you think?

Remove the dome light and clean the antenna connection where it plugs on to the base....sometimes just unplugging it and plugging it back in will fix this...or the base or cable may have to be replaced if corroded.....t-25 torx
could be intereference, which would be weird coming from those sources..... so yeah, disconnect and reconnect the antenna.
Electrical noise. Most likely from alternator. Check grounds, especially where Alternator bolts to engine.
