Ive got the Kury Covers with the Blue lights in them. The install is very straightfoward. I havent had any problems with them yet. Id say total time to install was about an hour and a half. And a lot of that time was spent trying to figure out where I wanted to run the wiring and hide the switch housing. I ended up securing my switch housing to the cover of the fusebox (its behind the side cover on the right hand side of the bike).
I just moved the fuse location sticker to the side cover, so I can identify all the fuses still.
The only bad thing is you have to pull off the side cover to turn the lights on and off.....small problem, but no big deal.
Hope the info helps.
