How does a flasher work

I have an alternating flasher from Tridon. Marked as below.

Do you mean, how does it work, or how should you wire it up?

I'm pretty sure that "L" means "load".... an electrical load that is.  Therefore, attach the positive lead of each light, to each of those L terminals.  And then you have only one terminal left over....attach that to the positive output from whatever switch you're using.

Again, this is just my opinion.  I believe it will work, but don't blame me if something breaks.

I tell my guys that a flasher is just like a auto-reset curcuit breaker..

when power goes thru it to a light or horn, it will draw current which in turn will heat it up and 'blow' it like a fuse, as it cools down, the contact resets itself allowing current to flow again.... and starting all over.. best way I can think of to explain it..
