Led electronic flashers ???

[66zz430]

I understand Led taillights requires an electronic flasher.
Now if leds are used in the front and rear lights then 2 electronic flashers are recommended.
So if one flasher is for the turn signal what is the second for ???

[NOT A TA]

I might be for the 4 way flasher.

You only need one if you don't have flashers. PM sent
