Hi Fred,
Thanks for your reply,
I started out by placing a medium radio-mast in a very obvious(ly wrong)
location where I could find it at night to observe its current behaviour.
With 098a it doesn't so much flash as twinkle. (albeit with a 1 sec period
of bright twinkling followed by a 1 sec period of not so bright twinkling
but definitely not an on/off behaviour)
I guessed that this was to simulate some random behaviour was observed from
these type of lights when flying. I started on a section that was originally
<animation>
<type>timed</type>
<object-name>StrobesOn</object-name>
<object-name>StrobesOff</object-name>
<use-personality type="bool">true</use-personality>
<branch-duration-sec>
<random>
<min>0.9</min>
<max>1.1</max>
</random>
</branch-duration-sec>
<branch-duration-sec>
<random>
<min>0.9</min>
<max>1.1</max>
</random>
</branch-duration-sec>
</animation>
I adjusted the min/max numbers up and down both synchronously and
asynchronously but couldn't observe any logical pattern to the way the
lights behaved in intensity or timing.
My guess is that the <random> function has something to do with this.
Looking at it though, I think the random-ness is more to do with a slight
variation in on/off duty cycle.
Should I be able to observe a distinct on/off behaviour of the lights?

Radio towers have flashing lights. See
