My Silverwing had parking lights back in '83, and I think it shared four-way flashers with my two Concours. I really wish we had those on the NT.
BTW, I had parking lights on my NT for about 20 minutes this morning. I'd been carrying a Coffee Mocha from McDonalds in my DayPack tank bag. It was too big to get securely into the bag, and was leaning on my chest. When I stopped and put the bike on the sidestand, my belly pulled the lid up and I was wearing Coffee Mocha on my light blue shirt. That threw my parking routine off and fifteen minutes later, as I was getting a haircut, someone came in and asked "Is that your bike?" I was afraid it had been hit or blown over in today's gale. I said, very tentatively, "Yes..." and was relieved when she said "Your lights are on." I went out and turned the ignition off and was relieved when the haircut was done that the bike started.
