Hello everyone. I am exploring the possibility of lighting a home made marquee of the word "CHICAGO" for a dance stage performance with BATTERY POWER. I would greatly appreciate any advice or solutions for this project if anyone has any good ones. My current thought is trying to light a store bought string of 75 to 100 bulbs of the G40 look using a car battery or similar as simply and cheaply as possible. I only need 5 minutes of light at most.
