If you have a headlight and tail light.......turn them anytime you're riding. Many motorcycles are wired that way now so the lights are on when the key's turned on.

There's nothing as potentially dangerous on the road as a woman talking on her cell phone while driving her SUV with a M.A.D.D. sticker on the rear bumper. (and Baby Onboard caution sign in the rear window) Fortunately there hasn't been an aircraft company who wanted to market a line of "flying" SUV's to them.
