I have a 1998 Ford Explorer that has a timer for the headlights. Apparently it's messed up because the headlights stay on WAAAAAY longer than they should. I know it's a safety/convenience feature, but it's draining the battery...even a brand new one I put on a month ago. Is there a way to disable the "timer" so that the headlights shut off when the motor does? Thanks in advance for your help.
