This Outdoor Timer features Interruption-Free Programming and prevents Headlights, Porch Lights and Street Lamps from interfering with the unit. The unique positioning of the outlets accepts most low-profile, right-angle and transformer plugs. The Photocell Activated components will activate the programming or reset only after the programming cycle has completed. Multiple timer options include 2hr., 4hr., 6hr., 8hr., Dusk-to-Dawn, or Always On settings.
