On my 2009 R3T...Very well-designed and well-made. Was a very easy install. Everything fit perfectly, instructions were clear. Overall, I like it very much. Increases visibility to oncoming-motorists, and that's a good thing.
I installed a Honda line light bar on a VTX I used to have, and it was a P.O.S., compared to the Triumph piece.
To anyone considering auxillary lights for their tourer, I highly recommend the Triumph piece.
There is a switch for the Aux lights on the left switch housing, right next to the headlight low/high beam switch.......at least there is on my R3T. It's already wired into the harness under the gas tank. The light kit is Plug & Play.
