I'm trying to figure out how to make a simple circuit for my car. I have a very basic understanding of electronics and I thought I had this figured out, but the more research I did into it, I realized that it wouldn't work. Basically, I'm getting new headlight units that have Daytime running lights built in, but my vehicle doesn't have that capability. So, here's the basic outline of what I'm trying to do. I have two power inputs that the circuit needs to determine if the daytime lights will run, one from my accessory port on my stereo and the other from my regular headlights when they are manually switched on. I thought I would use two transistors as switches to do it, but it doesn't look like it will work. Basically if there is power from the accessory cable, but not from the headlights, then the daytime running lights will be on, but if there is power from the accessory cable AND the headlights, then the daytime running lights turn off. The reason I am using the accessory cable is so that the daytime running lights aren't on when the car isn't on. If I could get a better understanding of what to use and how, maybe with schematics would be even better, I can read and understand those for the most part, that would really help me out.
Thanks in advance!
