Submersible Halloween lights allow a wide range of innovative decorating schemes. They can be placed in a water-filled vase and used as a centerpiece, in a pool, or wherever there is water. Or, they can be used out of water. Since they are waterproof, outdoor use is not a problem.
The things I would recommend that you look for include the words battery operated. A battery operated light string does not connect to your electrical supply, so if it does short out the damage is likely to be confined to the string of lights. Another feature that is highly desirable is remote controlled. It can get messy reaching into water to turn lights on or off, especially into a full vase.

The origin has lost its meaning over the years. Now it is a time for parties, and the lights are for decorations only.
Considering the pagan origins of Halloween we can't do much without the proper lights. Everything starts and ends with the battle between darkness and light.
I suspect there will be even more options by next year. If you can keep the battery pack dry there are others available now.
This is a wonderful way to light up for the holidays and special events.
