After having attaching a trailer hitch to a Volvo V70 2005 the tail lights keep glowing even when ignition is off. Therefore I have two questions:
- Is it normal on some cars? If not any ideas what might be wrong? Tried with some of those extra lights for bicycle carrier racks. Same things. Lights don't turns off.
- Will the battery drain even when the trailer is unplugged if the car somehow sends signals to the trailer socket.
