This must-have light pack offers three optional modes to suit your needs: security light mode, permanent on all night mode, and smart brightness control mode. The motion sensor detects movement up to 26 feet within a 120-degree angle, ensuring enhanced security while the high-efficient solar panel boasts a remarkable 20.5% conversion rate for energy-saving benefits. We can confirm that these lights are waterproof and heatproof, designed to withstand extreme weather conditions. We love using the security light mode both for lighting up areas where we are working or playing at night and for our safety. We mount these on heavy-duty suction cups located at key points around our rig when we pull in for the night. These lights are much brighter than we thought they would be! But not so bright as to bother our campground neighbors.
