The Browning 10mm Ballistic Lite is four times as bright as an ordinary pocket light. It clips neatly into your shirt pocket like a pen, and comes with a bore-light adapter for close inspection of your gun's barrel. Other handy accessories, such as a night-vision lens and a lanyard attachment, are also available. Comes in black, orange, yellow, and olive-drab green. About $10. 800-333-3288 for dealer information.
