You'll always be able to find your favorite drink when you light up your cooler with the HT cooler light. It easily installs on the underside of your cooler lid to provide 40 lumens of light. Once attached, you can set it to the auto-on Mode and the motion-sensing technology will turn on your light when you open the lid and turn it off when you close the lid. Perfectly designed for use inside your cooler, it's water-resistant and the LED run cool so they won't contribute to ice melt. The cooler battery lamp is a sports induction lamp, and the switch for turning on the lamp is installed on the cover of the incubator. When the cover is opened, the lamp automatically lights up, and when the cover is closed, the lamp is extinguished. The lamp is suitable for night illumination when traveling outdoors, it has a certain waterproof function, and does not affect the insulation effect of the cooler.
