I bought an electric scooter a few weeks ago to drive short distances around my neighborhood. I like it very much because it's very convenient for that purpose. The only downside to these scooters is they don't have a working taillight to drive at night. Most electric scooters only have a brake light.
This kind of annoyed me but i realise why. There is nothing to mount the taillight on since they don't have a seat like a bicycle does.
So i realised the best thing would be to get a separate taillight that you can clip on the back of your belt.
I use one like this: https://amzn.to/2zX5Uu8
Just make sure your clothes are not hanging over the light.
