Hi,

Anyone come up with a solution that would turn the headlights off automatically after the car ignition is off like the newer cars?

Thanks,

Joe

The simplest solution I can think of is a relay set up off the ignition power. Ignition comes on, sends power to the headlght switch so you can turn them on or off. Ignition off, no power to the headlights. If you want to get fancy you could grab a DEI relay used on remote starters etc for the turbo cool down. You can adjust how long the power stays on..

Thanks I will look into this DEI relay option. How many amps do you think the headlights pull?

Thanks,

Joe

Are you just looking to shut down the power to the headlights when the engine is off as protection from leaving the lights on accidently?

Initially I just wanted to make sure I don't forget to turn my headlights and/or parking lights off when I turn off the ignition. But if I can have the lights shut off after say 30 seconds that would be much better. On the 69 Camaro the main power to the headlight switch also powers the dome light so having the power turn of after 30 seconds would not leave me in the dark in the car after the ignition is turned off.:hurray:

I left my parking lights on the other day and it killed the battery which started me thinking about what I could do to avoid this problem in the further.

All,

Just a quick update, I have ordered a DEI RELAY MODULE PULSE TIMER NEW 528T off of Ebay for $11.49 should be here in a couple days. Looks pretty simple to install. I will let everyone know the results once I get it wired up.

Thanks again,

Joe

You can try that but I don't think its what you want. You need a time delay de-energize relay. This is a link to an automotive relay that should do what you want.

Hummm, I guess I will see but the information on this was:

The 528T module is a timer-controlled relay which temporarily connects or disconnects circuits for up to 60 seconds, so you can customize your alarm system to allow several applications to trigger in a timed sequence or to allow features like delayed arming. The 528T Pulse Timer module can even provide a "wait-to-start" trigger for remote starting diesel vehicles. The 528T features an adjustable timer up to 60 seconds with a built-in 15A relay. The pulse timer can be trigger by a positive or negative pulse.

So, your headlights will only stay on for 30 seconds with they key in the off position?
Advertised to stay on for 60 sec.

You might want to read this from the relay vendor. They explain it very well.

TXSGAMBER,

Have you used one of these relays before for this? I found this comment on a review of this relay. Seems this person could not get this to relay to work with the ignition switch. Don't know if this is a user error or an issue with this relay. Read review section...

Thx

Not sure what the person in the Review of that relay was trying to do. He even says in his review it worked fine on the bench. It sounds like he was trying to give the relay a short pulse to energize the coil and that will not work. In your case..if you take 12 VDC that is hot when you turn the ignition on and pass it thru terminals 85 and 86.That will energize the coil on the relay. Pass the 12 VDC output from the light switch thru the relay on terminals 30 and 87A so that when you turn on your lights and the ignition is turned on your lights will stay on. If you turn off your lights using the light switch, they will go out immediately. IF you leave the light switch on and you turn off the ignition switch and the 12 volts from the switch is no longer on, the relay will not drop out until it reaches the time you have it set for.( 2 seconds to three minutes based on the relay i recommended.)

Well you were right TXGAMBER, the DEI 528T will not do what I want it to do. So I have executed plan "B". I ordered the
Beuler BU508TD 12 VDC Automotive 4-Pin SPST Time Delay Relay with adjustable timing


it should be here early next week.

Why not a buzzer to alert you when the lights are on and the ignition is off. A friend built one for me years ago that I have on my Camaro. It buzzes when the lights are on and the key is not turned.
I would really like the light to shut off. But let's call that plan "C" ;)

Do you have the instruction on how to build a buzzer?
