OxyLED T-04 Motion Activated Light, $15 with code OXYT04NL

Our readers have bought thousands of OxyLED’s T-02 motion-sensing light strips over the years, but if you’ve found them to be to annoying to charge, the new T-04 looks like a great upgrade.

Like the T-02, the T-04 can attach to basically any surface via the included adhesive strips, and will automatically light up when it detects motion in the dark. The main difference is the battery: rather than charging AAAs or plugging in a microUSB cable, the T-04's battery pack is fully detachable, and plugs directly into any USB charging port. I have a couple of these set up around my apartment, and they work extremely well.
