Solitaire Flashlight Red Hanging Pack by MagLite K3A036  Less than an ounce and about three inches in length, the Solitaire offers the same precision engineering found in every Mag-Lite. Using only a single AAA battery, its focusing beam is suprisingly bright for such a small flashlight. A spare Solitaire lamp is included in the tail cap along with an Energizer Alkaline battery and a sturdy key lead. It's also ideal for a keychain or purse.
