An accelerating charge radiates light. But in its own frame of reference it is stationary. So it does not emit light.
How is this explained?
Extreme Example:
A charge inside an elevator is falling in a gravitational field. The elevator is lined with a light sensitive sensor that triggers a chemical explosion that obliterates the elevator in mid-air.
Inside the elevator a man is reading a book. The charge is stationary in his free fall frame. The man finishes the book just as the elevator hits the ground.
