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.

I have the blinkers do that on all my cars with just the brake lights
out, the other lights will light but not blink due to the 2nd filament
in the bulb being burnt out. (learned this at the expense of "press hard
3 copys" at the side of the road.) the hazard lights generally are
they're own light bulbs, the spit is set up that way, but then again it
is a us car, don't know if things "down under" are different. hmmm
would have to call frank, but he wont be in tommorow as it's saturday
there tommorow here. damn time line. and it is always the first place
i look, although a corroded connection did blow it for my theory once,
(what do you want on a 35 year old truck). it will be interesting to
see if lord lucas has struck again....
