I installed the LED's on my '11 FHLTK a few months ago. I love the results, but they are not as easy to install as some might say. I installed the turn signals, brake/tail light and the rear fender tip light that combines running light and brake light. Allow yourself plenty of time to read and absorb the instructions. Once you think you've got it, allow several hours for removal and installation. Definately have a set of ball-end allen wrenches available, otherwise you'll spend way too much time trying to get the OEM turn signals screws out and back in with with new LED's. The only thing I don't like is that you gain the brake light feature in the rear turn signals, which means the rear LED's are not available in amber. Had I thought about it sooner, I would have bought a set of ambers for the rear and just not hooked up the brake light feature. I think red rear turn signals on a bike are not nearly as noticeable as ambers....but that's just me. I would buy the HD LED's again, but I'd pay to have them installed.
