Ideal for gun safes, closets, cabinets, drawers and corridors, this light bar features long-lasting LED lights. With ON/OFF/AUTO modes, the light bar can be set to illuminate when motion is detected. When set to AUTO mode, the LED light automatically turns on at night when motion is detected within a 10-foot range, and it automatically turns to standby mode at night 20 seconds after no motion is detected. Easy to install, these lights require AAA batteries, not included.
