I only remember reading about one motorcycle having backlit controls and that was a recent article in Motorcyclist. I cannot remember which bike, but I want to say it was a KTM.
Honestly I did struggle one morning on my way home with the high/low beam switch. I could not seem to find that large rocker switch and could not get my headlights to dim. The oncoming car gave a very brief flash of his brights but nothing more and I was swamped with guilt. As the car went past I could clearly see the "Sheriff" label on the door.
I had not had the bike very long at that point. For the rest of the ride home I chanted over and over in my helmet, "I will learn to operate my bike, I will learn to operate my bike..."
So, in as friendly a manner as possible I am telling you, Learn to Operate Your Motorcycle. The last thing you want to be doing in the dark is looking for tiny labels on your handlebars. Not safe.
If it helps you, imagine what a fighter pilot must learn to operate in the cockpit of a modern aircraft. Have you ever seen the various switches and buttons on the stick in an F-15? No time to look for the right switch in a dogfight.
