Headlights and taillights are on when car is running regardless of day or night and whether switch is in off or on. Headlights do turn off when switch is placed in parking lamp setting. The radio and interior lights switch between dark and light so assuming the light sensor is working. This started about 3 months ago. Before, the daytime running lights were the only ones on in the daytime. I am assuming this is going to burn out bulbs much sooner. I cannot figure it out. Any advice greatly appreciated.
