Aptoyu via Amazon offers its Aptoyu 10-LED Waterproof Wireless Motion-Sensor Solar Light 2-Pack for $14.99. Coupon code "5CHN68KE" cuts it to $9.99. Plus, Prime members receive free shipping. That's tied with our August mention as the lowest price we've seen. (It's also $9 under the best deal we could find for a similar 2-pack elsewhere.) Features include ABS construction, sensing range of 10 to 16.5-feet, sensing angle of 120-degrees, and IP64-rated waterproofing. Deal ends January 31.
