12 Volt Direct Current Timer Designed to control on/off times for other Yeti Solar 12 volt products, such as a LightPortal, a LightPassage, or an Exclamation Light. Program a light to come on in the evening (never come home to a dark house!), or use it to deter potential thieves while you are on vacation, or use it to set automatic lighting for livestock. Installation is simple and fast with color-coded click-connectors. Comes with detailed instructions (including color photos). Get it installed and set your desired on/off times in under 20 minutes. Capable of up to 17 on/off times, repeating on your desired days of the week. Internal battery means you don't lose your on/off times even if the light runs out of power.
