Absolutely love these turn signals! They are stealth and low profile so you get that nice and narrow look on the S40. Install kinda sucked though. There are threads on the turn signals themselves and there are none on the rubber mounts so I had to drill out the holes on the rubber mounts to make them fit. Kind of a pain but given an hour or two in your garage you can figure it out. Wiring was easy and the video helps a ton with the fronts due to the extra running light wire up front. Definitely recommend if you're looking to keep your bike narrow and adding some cool looking blinkers
