Amazon offers the MPow Solar-Powerd Wireless LED Security Motion Sensor Light for $12.99. Coupon code EN7GWEJB drops it down to $10.99 Prime shipped. That’s $19 off the original price and the lowest we’ve seen. This is a security light that you can screw in any south/east/west-facing wall or post that will charge a battery all day and emit a light when activated by motion sensors at night. No wiring is needed and one screw is included (but another can be added for added strength). Motion sensor works at around 10 feet and it is weatherproof.
Note an 8 LED version is available for $15.99 but the coupon code won’t work.
