Installation
Installing the Sicass signals on my KTM 450EXC was plug and play. I had to remove the rear brake light/license plate holder, side plate and seat. Once these items were removed exposing the factory KTM wiring the signals were installed into the factory quick connect fittings.
Durability
One thing I can say I'm a few ride in and plenty of tip over conducted and so far they are still working and mounted to the bike.
Overall
So far I'm very happy with the way these signals look, and how easy they were to install. Anytime you can buy a plug and play aftermarket items it makes installation easier. Keep in mind if you're installing LED signals on both front and rear you will need resistors or Sicass Racing's Smart Flasher unit which is also plug and play. (Purchase)
