This might sound dopey, but just something to consider based on simplicity and no wiring mods, etc . . . But bicycle accessory companies have zillions of lights like that between them. There is an endless array to choose from. from flamethrower to regular "notice" mode. They have rechargable batteries. Mine give about 2 weeks of lighting before recharge, so its really not that bad. You can mount one anywhere on your MC. Take it off when you dont want it
