The Bayco Nightstick LED Safety Lights, Nos. NSR-2070, NSR-2072 and NSR-2078, have integrated Li-ion rechargeable batteries. The lights combine a full-size flashlight rated at 150 lumens for distance lasting 7.5 hours, with a flood/flashing safety light rated at 50 lumens for four hours. There are two body-mounted push buttons that control the two purposely separated and independent lighting functions. The top body mounted button powers the flashlight in either momentary or constant-on mode, and the bottom button controls the LED safety light. The NSR-2070 features a red and blue array of LEDs, the NSR-2072 features a red and while array and the NSR-2078 emits a blue and white alternating array. These water resistant lights include both an AC and DC power supply and include a one-year limited warranty.
