Headlights On With Lock/Unlock, Welcome/Leave Home

Hey all,



I am trying to set up a module that i can use to turn on headlights with lock and unlock so basically I have all things sorted out except one thing. I want the module to stop working if my headlight switch is set to the OFF position, so basically my switch gives negative ground to 1 of the wires when its set to OFF and i wanna use that signal to turn off the module but i cannot figure that out. I can do that with 5 pin relay but that would mean the relay will stay energised and will drain the battery. Does anyone know any other way? Like a transistor or something?



Thanks in advance
 
Your question reads like, "I'm at the dance with Mary, how do I ask her to dance with me". At this point we really don't know if Mary is on a date with you at the dance or if Mary knows you've been stalking her and you followed her to the dance - or something in between. The advice will be quite different in each situation - if we want to give any at all.

You'll need to give us more background about how you "got it all sorted out" to this point.
 
If I understand what your saying and asking, then just use the switch of the head lights. Put everything in parallel with the headlights. Of course I don't have a schematic, so take what I said with a grain of salt.
 
It sounds like you want to duplicate a DRL module, which turns on the high beams at lower intensity with the headlamp switch off. Feeding a negative ground wire to the "Park Brake Sense" input of the DRL module should disable the headlights. The headlight switch operates normally and overrides the active DRL module.
 
You can make a transistor based circuit alternatively. The circuit will consist of
NPN transistor (e.g., 2N2222 or similar),Resistors (appropriate values, typically 1kΩ for base resistor),
Diode (optional, for protection),Headlight module and Headlight switch.
