Ollny 400LED 132FT Christmas Tree Lights with Remote Control - 8 Lighting Modes & Timer Function, Waterproof Outdoor/Indoor Holiday Decorations for Christmas, Halloween, Parties and Home Decor

These are awesome lights. The color, the different tempos, the length.. But you cannot plug these into another string of lights of the very same brand and make which makes for extension cord set ups. The first picture is of the exterior outlet I wanted to plug them into and connect/ run the together with an exterior extension cord. The second picture is the end that you can connect another string of lights to but we tried with the second set we purchased and they wouldn’t work. It has the plug to connect to another string of the same lights like you would normally want to do with LED lights but these you cannot. The second string will not work and it dims the first set of lights. Plus, you cannot plug these into a heavy duty orange or green extension cord normally used for outside and longer extension lengths. These are only fully functional with regular white or brown interior type extension cords or outlets.Because we could install these lights where the extension cords wouldn’t be exposed directly outside because of our deck and only for the month of December we decided not to return them. The remote is nice but I found that they don’t work when plugged into extension cords so you’ll have to use the built in mode changers on the actual strings. We have four in total with these lights as we bought two of the white and two of the blue. After skillful installation and cords galore we set the twinkle setting once and made sure to plug them into an interior outlet so we can just flip the light switch on and off. Worth the initial hassle for us, because they’re so beautiful but I would’ve been happier to be able to connect the strings together, to only use one extension cord. But as you see from the pictures each string needs to be plugged in separately. Make sure to test them inside when opened and then again outside with the actual outlets or extension cords you have in mind, before actually wrapping or hanging them because that’s where you’ll find that they might not work or one string does and the other (connected) strings don’t, and/or the remotes don’t work. We found out the hard way and had to unwrap and take them down and almost returned them when I could understand why they worked when we plugged them inside the home first. And then rehang and install them when I figured out the multiple issues. I hope this long review was helpful.
