installed on 96 Honda XR250L street legal Enduro. Headlight is on with ignition on this model which is a heavy load on battery when not running. Do-Dad switch allowed me to switch headlight off when starting motor. Easy to install next to left handlebar switch. I connected switch's wiring into wiring loom coming out of handlebar switch. Almost looks like factory installation. The toggle switch is a little flimsy looking, but should work okay. Took me about 40 minute to install.
