OK,
So I am looking at this Mod, and then I was reminded after my girlfriend was driving it and forgot to turn the headlights off until we were already several feet away, that having a Saab with automatic headlights for the past 6 years creates some bad habits. I want to do DRL, but am also afraid that DRL, without auto-on headlights, leads to that potential of driving in low-light with just the DRL, so in an all-black E, visibility could be poor (don't want someone to hit me). Auto-on I am sure would add a whole extra layer of complexity to something that is a bit over my head.
In doing a search for auto-on, I noticed that auto-off headlights have been brought up a few times and shot down without fully-entertaining the concept, but realizing that auto-off could fix my fears if the headlights would just turn off with the key so I still have the ability for regular parking lights and full off lights, but can just leave the headlights on most of the time and not worry about night-driving. I have no problem with needing the keys in the ignition to have the headlights on, so it would be no real loss to me.
In all these schematics, I feel I could figure out which few wires to splice to accomplish an auto-off feature for all lights (when in an on-position on the indicator), but I am not that good with schematics, so I ask, what would the trick be to have the headlights turn off with the key?
