Update: I reinstalled ELS v1.05 and I can at least get the lights to turn on and they do correct sequences, but they don't flash. They're just a color.
EDIT: Also I forgot to mention, it lights up the area behind the vehicle as it should, but not the sides or front. Here's a screenshot: https://www.dropbox.com/s/mswh813ravn664e/Whytho.png?dl=0
