Meritline offers the Super Bright 3-LED USB Snake Light 2-Pack in Silver for $6.99. (It's the second option.) Coupon code "MLCKWND3NL1" cuts it to $3.99. With free shipping, that's tied with our September mention and $8 under the lowest total price we could find for a similar pair of lights elsewhere. (Meanwhile, Meritline charges the same for just one light.) It features an on/off switch and can be used with any powered USB port. Coupon ends after 200 redemptions.
