Never get caught in the dark without a light or a whistle/alarm to get peoples attention in an emergency. This section contains products that are easy to carry and cover both. Even if there is no emergency use the light to show the way to your car in the parking lot or see the lock to unlock the car. How about getting to the door of your house. Keep a light with you and add a whistle/alarm in case of emergency. An attacker doesn't like attention, so the last thing they want to hear is a loud whistle or alarm.
