You mean you've never seen a VX's light burn out, or you've never seen a blinker announce it?

The notification has been standard for years upon years. Blinker modules have been based around voltage draw, which means that it doesn't cycle until the light is fully lit. LED has reduced current draw, which the module falsely interprets as a lack of current draw, and thus cycles more rapidly.

Literally ever car I've ever owned had a rapidly cycling blinker when a bulb burnt out; VX isn't any different.
