My vehicle has begun all us sudden flickering headlights from low beams to high beam when driving and also it ay the airbag safety light turn on with the locks also doing a closing and opening while driving.
The headlights continously and irregularly flicker between high and low beam while driving at night. I have no control over it and cannot turn off the high beams when they activate. This is highly annoying to drivers ahead me, as they believe I am trying to get their attention (or be obnoxious). In these times and the legalization of open carry weapons in the state of Florida, this can be highly dangerous if the wrong person is aggravated by unintentional signaling. I have already had issues on the road with drivers not happy with the high beam flicking on and off at them while driving on the road. They have become very aggressive, following, slowing down, honking at me because they think I am being impatient or trying to tell them someting is wrong. I spent $2000 in January 2025 trying to get this fixed and it has started (December 2025) happening again.
