Just thought I would share my experience swapping the stock 2 wire incandescent front turn signals over to LED.
I went with a set of these which were recommended elsewhere in the forum:

These are 3 wire LED signals with the 3rd wire meant to power the white running light. I taped over this connection and just used the yellow blinker wire and ground. This means a yellow running light instead of white, but that was fine with me.
I tested without resistors and as expected got a fast flash behavior. I added a 15Ω / 10W resistor per side which were left over from some Rizoma signals I used on another bike, which got me a normal blink rate.

I was a bit concerned that these resistors were undersized, but after a couple of hours of riding I checked them they were barely warm to the touch. This makes sense I think because this year AT outputs somewhere between 6-12V to power the running light which would be:
P = V^2 / R
= 6^2 / 15 = 2.4 W @ 6V and
= 12^2 / 15 = 9.6 W @ 12V
My understanding is we do get the full 12V when flashing, but this is not constant so I'm not too concerned.
As far as mounting goes I used the stock mount but had to remove the metal piece on the inside to get enough clearance to thread the nut onto the bolt. Overall I'm quite pleased with how things turned out.
