Electrican Question
I am a noob when it comes to electrical wiring so I hope someone has an answer for me. I want to make it so that a light can draw 12v directly from the battery but only turn on when a circuit with less than 12v is activated. How do I do this? I know I need something other than a switch. Is that what a relay does? If so what kind do I need? Thanks.

Ok.......... I thought about this for a while as what you are saying is confusing as hell LOL
but here it is.
What you want to do is to have a neon on the trunk or in your car to go on when your system goes on. You need to get a relay switch and connect the remote turn on lead to it (the cable that makes the amp turn on). You also need to provide the 12V power to it and the output will go to the neon. I hope this is what you wanted.

Well you need to have constant voltage on the line... but if the lights blink then I giess (but Im not sure) that the neons will blink.

The relay is what you want. I would give you a link to how to install / implement, but I can't find it. If the faqs is still at the top of the audio and electronics forum page the install doctor should have that info.

correct me if im wrong, but if the wire that u use for turn on current (remote wire) doesnt have a constant current, then the relay will open and close the circuit whenever the current in the turn on wire changes

That's correct. It will be the on/off switch. The current for the lights will be supplied by the always on input.

Well today my friend went a bought a relay and just ran it off of the fuse box. So whenever he turns his car on the angel eyes come on. He is going to put a switch in it to but for now its working. Thanks for everyones help!

what im trying to say is this: if u connect the turn signal wire to the relay as the switch current, then the output wil switch on and off with the turn signal, so thats *** backwards my friends

No, you are wrong. The turn signal wire goes to the magnetic switch. The Positive from battery supplies the power. So everytime the turn signal goes on and off the items powered from the relay will get full battery voltage minus the voltage drop in the wireing and relay.

Okay, you agree that we were right the first time then? You disagree, you agree. I could care less but it is frustrating. Make up your mind already or agree that you don't really know. I thought you wanted the neon to blink with the turn signal but that you wanted it to turn all the way on instead of only low voltage?

One of the lights in the corner is always on with the headlights. The other one is the turn signal that flashes. The comment was directed at friendhasmax who contradicted a statement and then contradicted him/her self.

what are ur credentials jmax? do u hold a degree in electrical engineering? or atleast an associates in electronics technology? or maybe u didnt understand what i was agreeing/ not agreeing to. i happen to be on my way to finishing my BS in electrical engineering. i think i know what im talking about

Well, for your information I don't have any credentials. That's okay, I don't respect someone for credentials anyone may get at a 4 year college. Would you mind telling us exactly how much successful experience you have outside a textbook?
Go back and read your posts. You will see that what I said was in direct response to your inability to determine your stance on the issue at hand.

anyone can get a BS in electrical engineering? thats funny, i thought most people couldnt even handle the math. by the way, all the **** that u deal with came from what electrical engineers have came up with. so i think u better respect someone with the credentials, and yes i have plenty of hands on experience with audio systems, both home and mobile. all of my instances have been successful. its easy for someone to wire up a stereo system in a car by following directions. but can u tell me honestly that when a problem arises u know what the problem is exactly, and what may have happened in order to cause that problem. in order to solve the problems that come up with mobile sound systems u need to know the theory behind the electrical work involved. this is where the engineer comes in man. take alternator whine for example. do u kow what causes it exactly? someone might tell you how to fix it, but do u know why it works? who is the person that came up with the solution to that problem? it was the engineer, u know, the person who's credentials u dont respect cause u know more about stereos than he does, simply cause u have hands on experience. well u wouldnt even have a car to drive if the engineer didnt have his textbooks fool

Settle down little boy. Don't beleive every fool who says they have no creditentials. I had a choice and chose not to be a EE. That was a choice. Nothing forced on me. So sit back down behind your textbook. When you come up with a theory on your own, then publish it. But sit down in the meantime and reread the above posts where you agreed that you disagreed.
