If, as Ricky Nelson sings, you're "a traveling man" (or woman), the car mounts by Arkon Resources will do a good job of keeping your Visor secure and ready when you're in your car.  The mounts are a little pricey but will keep your Visor secure and at arm's length when you're pulled over at the side of the road. Just make sure you secure the suction cups well if you have the windshield model.
