I found a solution. In an example I found on this site, the fix given was to add the line
Texture=fx_2.bmp in the [ParticleAttributes.0] section of the fx_wos_l049_beacon.fx file.
What I also noticed, is that above that line in my version of that file, the value was set to 0. As in...
Blend Mode=0. Whereas in the post containing the 'fix', it had the value of 2. So I changed that as well and as I said, it now looks fine. A proper flashing red light. Here's the fix that did it.
[ParticleAttributes.0]
Blend Mode=2
Texture=fx_2.bmp

Thanks Pat!
Now. How about an official fix eh? Shouldn't need to do this, you guys are better than that.
Thanks.
Steve.
