Hi Mike
It seems to me that there are two options available to us.
Option 1 is to install Flarm.
The problem is that it only works when we equip every aircraft
with this system. In the absence of corresponding regulations
this will (unfortunately) remain a nice dream.
Option 2 is to fit strobe lights.
Granted, it might not be quite as effective under all conditions
but it is a huge improvement on the current situation. The light
intensity of a 20 watt flashlight needs to be seen to be believed.
An additional 7Ah battery will be more than enough to power the
new generation LED strobe lights even for long flights. Aircraft
with solar panels might not even need an additional battery.
In conclusion, fitting strobe lights makes you by far more visible
and hence safer. Fitting Flarm does nothing (unless all of us dig
deep and install them).

So how do they compare in brightness to strobes? Dick Johnson did some
strobe testing a few years ago and concluded they were effective under a
small range of conditions.
Lights also mean the other glider must be in your field of view and
saiplanes are more restricted than people think in this way. Seems likely
that the false negative cases might be quite high here.
