My car has 58960 miles.
My car has an automatic transmission.
If the lights are flashing constantly, then there is a short between the flasher unit and the turn signal and highbeam circuit that is causing the issue. If the lights are flashing a little and looking like a flicker, then there is a loose wire on the main light switch.
