I had them on my Gold Wing and they are great. My passenger loved them as she could see what turns I was going to make before I made them. When I mounted LED strips on my RT mirrors, Muth did not have anything available for the RT's. I wrote and told them they should develop a kit for them just like the Gold Wings. Many others must have done the same. It looks like they have developed a kit for the RT's.
However, the 'Wing is a simple replacement -- easy to take out the mirror, put in the mirror, wire it and you're done. Very simple. I just took a look at the "instructions" on the Muth site for the RT. They require you to disassemble the mirror housing (tricky at best), then heat the mirror glass with a glue gun to soften the glue and separate the glass from its backing, etc, etc. Not a job I would want to tackle. If you could ship them the complete mirror and get it done by them, great. But it looks like for $219 they send you the kit and instructions. For $20, my LED strips look very built-in and work great. There are numerous threads here detailing different approaches by folks using arrows, LED strips, etc. Muth would give you the most professional OEM look, I admit. But you might want to take a look at the instructions first. If they make you uncomfortable, give them a call to see if they would do the installation. Just a suggestion...
