Hey, relax, after all this is the world-renowned friendliest we-derail-every-topic-you-serve-us™ board this side of Riedquat—nah, what do I say—of Oresrati!
... (Offset is supposed to be brightness control for always-on-flashers, right?)
I don't follow you here. Where do you have this particular bit of information from?
That's not an information, but an assumption... and a question.
I assumed that, if offset is 0, flashers will not be lit (actually, I had to set the offset to other than 0 to get lit flashers for some reason.. probably forgot to convert commas into dots with copy-pasted floating point position coordinates), and the intensity of the light would follow the sine offset. Clearly, that is not a case. Any offset gives the same half-dimmed flasher.
Edit: .. and I got white flashers!
