Yes, there is a way to turn them off: wire in a switch! Not being a wise guy but US bikes are mandated to have headlight on as Daytime Running Light (DRL). The Euro and Asian models have a switch on right grip where we have a shiny, black plastic cover. Been studying this in wiring diagrams for months and it looks like the wires are there just no switch. I think I have cooked up a different way just have not done it yet. For today, when you turn ignition on, the lights are on.
