I recently installed the Cyclops LED kit into my bike. They are an incredible upgrade, probably the best one I've done to the bike.
The installation is completely plug and play, without any modifications to the bike or wiring. I had no issues with the Canbus system. It will initially flash an error code, telling you the headlights are out. The error code will go away and stay away once you cycle the ignition. Make sure your DRL setting is turned off, so the DRL will be on with the headlight and not cancel it out during the day hours.
A little back story about Cyclops. I purchased the LED kit through my local shop and was reading installation instructions on Cyclops' website. I noticed the website was advertising a new improved kit, which had drivers that did away with the resistors.
I couldn't tell if my kit was the new one or old, so I called Cyclops. They told me I had the older version, but wanted me to have the improved kit. They asked if I'd bring my old kit to them for an exchange for the new kit. I thought this was amazing, especially since I didn't purchase the kit directly from them.
The staff gave me a tour of the facility and let me hang out a bit. If you can, I'd probably order the kit direct from them, so you can have the awesome customer service.
