keen 6 Report post Posted March 31 My daily driver has the lights on auto. Because of this in the older car I have the habit of leaving the lights on and returning to it later to find the battery is flat. I have an E90 and a mini cooper S both of these have a safety system that turns the lights off after some minutes to save the battery. I read once somewhere that you could fit a device that replicates this. Does anyone know of these and if so where do I get one? Quote Share this post Link to post Share on other sites
