Always carry a small flashlight, but one that is no bigger than your hand.  It should be able to produce at lease a 6,500 peak-beam candlepower.  Whether you’re inside or outside the club a light this powerful gets the patrons attention.

Note: Flashlights that use lithium batteries can not be used for a long period of time.  For example, if a situation requires you to use your flashlight most of the time during a single work shift, chances are the next time you work the batteries will die.  These types of batteries only have about 10–15 hours worth of life to them.
