Review on Lipctine 4 PCS USB LED Car Interior Atmosphere Lamp, Night Light Mini LED 🚗 Decoration Light, Ambient Lighting Kit, USB Charging for All Vehicle Models, Bright White Interior LED Lights by Brett Slater

I bought this as a night light in my caravan as it has multiple USB ports. So when I got them I tried them out in a USB (charging box) at home and they all glowed and looked good. But when I took them to my trailer, none of them worked in any of the USB sockets. I have no idea why because the sockets worked fine for other things I've tried in the meantime. Anyway, I've had them too long to return and now remember to test them where you plan to use them as soon as you receive them in case they don't work like mine.
