Their lights usually have a plug on one end and a socket on the other. Ppl put them around the exterior of their hoses, then realise they did it the wrong way, and the socket end is near the outlet they wanted to plug them in.
Or they mounted two strands of lights, and where they meet up it’s either 2 plugs or two sockets accidentally.
I like flying goose brand. IIRC it’s actually made in the sriracha region in Thailand , and it’s the brand huy fong copied the bottle design from. Many supermarkets sell it here.
And here I am using FreeBSD.
