That is a fairly widespread practice (even TRs), for the obvious reason
that it tells the driver that a bulb has failed. Usually however, the
internal turn indicator light stays on and does not blink or blinks very
slowly. I also seem to remember that the hazard lights always blink at the
same rate regardless of the state of the bulbs, but I would need to check
that.
I just think that it would be too much of a coincidence for both front and
rear bulbs on one side to fail together. It is not impossible, but it is
not the first place that I would look.
