Most probably a fauly brake light switch and brake lighs are flashing thus stressing the bulbs. Reset the switch or change it. Regards Peter

Hi,

I know it’s an old post but mine was doing the same. The bulb should be a double filament. When the brake light failure message came on I replaced the build with an advised one but they kept blowing when I had my night lights on. Checked the other side and it’s a double filament because it’s a stop tail bulb.
