Setup and Installation
- Planning the Layout: Determine the desired location for your string lights. Ensure the path is clear and there are no obstructions. The string is 20 feet long with 10 sockets spaced 2 feet apart.
- Mounting the String: Securely hang the string light strand using appropriate mounting hardware (not included), such as hooks, guide wires, or zip ties. Ensure the sockets are facing downwards to prevent water accumulation. The heavy-duty 16/2 cord is designed for outdoor use.
- Installing Bulbs: Carefully screw each S14 incandescent bulb into the E26 sockets. Ensure bulbs are fully seated but do not overtighten.
- Connecting Multiple Sets (Optional): These string lights are linkable. Up to 10 sets (total 200 feet) can be connected end-to-end safely. To connect, align the male plug of one set with the female receptacle of another and push firmly until secure.
- Power Connection: Once all bulbs are installed and the string is securely mounted, plug the string lights into a standard 120V AC outdoor-rated electrical outlet.

Maintenance
- Bulb Replacement: If a bulb goes out, the rest of the string will remain lit. To replace a bulb, first unplug the string lights from the power source. Carefully unscrew the old bulb and screw in a new S14 incandescent bulb (11-watt, E26 base). Use the included spare bulbs or purchase replacements from Feit Electric.
- Cleaning: Periodically wipe the bulbs and cord with a soft, dry cloth to remove dust and debris. Ensure the lights are unplugged before cleaning. Do not use harsh chemicals or abrasive cleaners.
- Storage: If storing the lights for an extended period, unplug them, allow them to cool, and gently coil the string. Store in a cool, dry place away from direct sunlight.
- Fuse Replacement: This product is equipped with a fuse in the plug for overload protection. If the lights do not turn on, the fuse may need replacement. Unplug the string lights. Slide open the fuse access cover on the plug. Carefully remove the old fuse and replace it with a new fuse of the same rating (typically 5A, 125V). Close the fuse cover.
