Underglow problem
 

Hey everyone, having a problem with a car other than my Civic at the moment. I have underglow installed on the car and up until this point it has worked fine. It is wired so that it may only be turned on when the headlights are on, and the remote for the underglow has sent an on signal. Recently, the underglow immediately turns on when the headlights are turned on and the remote does nothing. If it matters, it did rain hard a few days ago and the control box is on the bottom of the car. Any info is helpful!
