(June 4, 2016) Since I purchased it last July, I've been dissastifed with the visibility of the rear turn-signals on my 2015 Ultra Limited Special Edition (FLHTK) touring bike. So today I added Harley-Davidson Electra Glo LED Saddelbag Mounted Run/Brake/Turn lights -- part number 67800241A. I chose the version with red lenses in a chrome housing because I felt they best match the existing rear lights.
I was able to install them myself with little trouble in less than an hour, and at least ten minutes of that hour was just to empty my saddle bags. :-)
The wiring is all modular and plugs into existing cables. The instructions provided in the box are very clear, including the illustrations. Be careful to position the lights where you want them before removing the adhesive cover. Also be sure to have the saddle bag covers closed and the bags mounted so you can work the lights into position without having the bags move around on you.
These bright LED lights retail for $229.95. So far, I recommend them. (Let's see how they hold up in bad weather and long miles.) I've included a video (below) to show you how bright they are.
As always, keep the shiny side up!
